The Role of the Changing Labor Market
and the Changing Nature of Work
in Older Workers’ Work Experiences
and Health Outcomes
CHANGES IN THE LABOR MARKET
In the past century, the median income of Americans has increased
substantially, many aspects of their working conditions have improved, and
their average life span has increased (Council of Economic Advisors, 2002).
Nevertheless, some recent economic and workplace trends raise concerns
about the health and safety of older American workers. Income growth has
been uneven across the income distribution, and while the health and safety
conditions of workers in some occupations and industries have improved,
this has not been the case for all workers. For instance, as we discuss in
Chapter 6, changes in the nature of work (increases in stressful job charac-
teristics and work organization) are associated with increased risk of car-
diovascular disease and other illnesses or disorders commonly experienced
at older ages. Unfortunately, there is limited evidence on how these trends
are affecting the health and safety of older workers. More generally, there is
controversy over the validity of the illness or disorder and injury data that
we now collect to measure these trends (see Chapter 6).
Important changes in the structure of the American economy over the
past several decades have affected older workers’ occupational distribution,
income, availability of retirement and disability benefits, job security, union
membership, and, potentially, their health and safety. Employment in the
United States has gradually shifted from the production of goods to the
service-producing industries (U.S. Bureau of Labor Statistics [BLS], 2003).

depending upon one’s point of view (Kalleberg et al., 1997; Standing, 1999).
Deregulation, increasing reliance on voluntary standards, privatization of
government services, and an emphasis on market forces to meet societal
needs are all key aspects of a new American economy, which has grown
substantially and increased employment, especially over the last decade of
the 20th century, but has resulted in workplaces that still contain substan-
tial health risks for some workers (Levenstein and Wooding, 1997).
Shift to Service Industry Employment
In the mid-20th century, about a third of the American workforce was
employed in manufacturing. Today, not much more than a tenth are so
employed. About 80 percent of the workforce is in the service sector. In the
economic downturn after 2000, about 10 percent of manufacturing work-
ers lost their jobs—about 1.9 million workers. On the other hand, service
industry employment has continued to increase by almost 2 percent (BLS,
2003).
Table 3-1 shows the occupations with the largest expected job growth
between 2000 and 2010 (Hecker, 2001). The large, high-growth occupa-
tions include a disproportionate share of low-wage service sector jobs, and
60 percent of these high-growth occupations are in the lowest quartile of
median hourly earnings. However, many smaller occupations that require
advanced training and pay high wages will also expand. Hence, the skill
distribution of the future workforce is likely to increase somewhat faster at
the high and low ends than in the middle.
These trends have important implications not only for income but for
benefits received by older workers, including health and retirement ben-
efits. For instance, after substantial increases in employer pension coverage
from the end of World War II to the 1980s, primarily obtained through
collective bargaining, pension coverage has remained constant at about 50
percent for all workers. Also, a significant percentage of workers are still
not covered by employer health insurance. The end of this trend toward
growing pension and health coverage was due in part to the shift of jobs
from more heavily unionized manufacturing industries to service industries.
Nonstandard, Alternative, and Precarious Employment
One aspect of increased employment flexibility is the rise in nonstandard,
alternative, or precarious work arrangements. Such arrangements include
employment for a temporary help agency or contract company, independent
contracting, on-call work, day labor, and several forms of self-employment
(National Research Council, 1999). Nonstandard workers typically receive
lower wages (or salaries) and fewer health and retirement benefits than

workers with similar skills who work as full-time, regular employees
(Houseman, 2001; Mishel, Bernstein, and Boushey, 2003). Older workers
are more likely than younger workers to be employed as independent con-
tractors and other kinds of self-employment (Houseman, 2001). On the
other hand, workers between ages 45 and 64 are less likely than younger
workers to be employed in a precarious forms of nonstandard employment,
including employment as agency temporaries, day laborers, contract com-
pany workers, and temporary employees. Workers who are 65 and older
are more likely to work in nearly all forms of nonstandard employment.
While available data suggest that nonstandard employment has been
increasing in a number of advanced industrialized countries (Quinlan and
Mayhew, 2000), the long-term trends are difficult to assess in the United
States because comprehensive surveys such as the Contingent Work Supple-
ments to the Current Population Survey are not available before 1995.

U.S. workers in all nonstandard work arrangements (including part-time
employment) declined, falling from 25.3 percent to 23.0 percent among
men and from 34.3 percent to 31.0 percent among women. However, the
proportion rose during the following recession (Mishel, Bernstein, and
Boushey, 2003). One possible indication of the longer-term trend in non-
standard work arrangements is the rising fraction of workers who are
employed in the personnel supply services industry. The proportion of
employees on nonfarm payrolls who work in this industry rose from 0.3
percent in 1973 to 3.2 percent in 2001, although, as noted above, workers
between ages 45 and 64 are less likely than younger workers to obtain
employment in this industry (Houseman, 2001; Mishel et al., 2003).
The increased use of temporary employees and the practice of contract-
ing out pose challenges for the protection of worker health and safety. A
study of contractors in the petrochemical industry showed substantial defi-
cits in the health and safety practices applied to contract workers, deficits

that may have played a part in the promulgation of the OSHA’s Process
Safety Standard (Wells, Kochan, and Smith, 1991).
Trade Union Density
Another feature of the U.S. labor market is the decline in trade union
membership among nonagricultural employees from 24.1 percent in 1947
to 13.6 percent in 2000 (Hirsch, Macpherson, and Vroman, 2001). By
2001, only 9 percent of private sector workers were union members (BLS,
2000). This reduced the significance of negotiated work rules, including
seniority rules. However, the net effect of the decline in unionization—and
the consequently greater control over the workplace environment given to
management—on the health and safety of older workers, especially their
potential loss of seniority protection, is not clear and should be investigated
(Standing, 1999; Weil, 1991).
Immigration
Because of its high level of immigration, the United States may have a
relatively younger age structure compared to other industrialized nations
(Gibson and Lennon, 1999). On the other hand, as immigrant workers
grow older and settle in the United States, problems of racial and ethnic
discrimination may be compounded by age discrimination. The lack of
attention to the health and safety needs of minority workers may pose
problems for U.S. industry (Azaroff and Levenstein, 2002). To the extent
age dimensions of such problems have been studied, the focus has been on
young workers.
Trends in Income and Income Inequality
The consequences of the changing labor market structure on family
income are significant. While real median family income grew from 2.8
percent annually between 1947 and 1973, annual growth slowed to 0.2
percent per year between 1973 and 1995. Over the latter period income
inequality also increased (Mishel et al., 2003). The United States has greater
income inequality than other industrialized countries, and its level of in-
equality rose sharply over the 1980s business cycle (1979–1989). However,
the rise in income inequality was slower over the 1990s business cycle
(1989–2000), as the growth of real income for low- and middle-income
families outpaced that of upper-income families during the boom years of
the late 1990s. Despite this economic boom, hourly wages for men in the
bottom half of the income distribution were lower in 2001 than in 1979
(Mishel et al., 2003). In addition, income inequality began to rise again as
the U.S. economy moved into an economic downturn after 2000.

THE LABOR MARKET AND THE CHANGING NATURE OF WORK
A debate is now ongoing in the health literature with respect to the
importance of income and income inequality on health outcomes. As dis-
cussed in more detail in Chapter 4, income is associated with health out-
comes, and a health gradient has been found in many countries. (Lower
income persons have worse health outcomes than higher income persons.)
Hence, an increase in income over time should improve health outcomes.
But if proportional increases in income occur at higher rates for higher
income parts of the income distribution, they are also likely to increase
inequality in health outcomes, others things equal. Furthermore, it is argued
by some that income inequality itself has an independent negative effect on
the health outcomes of lower income people. (See Kaplan et al., 1996, and
Deaton, 2003, for divergent views on the relative importance of income,
poverty, and income inequality on health outcomes.) It is difficult to dis-
entangle the net effect of increases in income (in many groups) and in
income inequality on the health outcomes of Americans in general and
older Americans in particular. This is especially the case since serious ques-
tions have been raised about the validity of current (nonmortality-based)
illness or disorder and injury data in the United States (see Chapter 6).
THE CHANGING NATURE OF WORK
Trends in Working Life
Throughout the developed world, economic growth has been accompa-
nied by some of the same trends in income inequality and in the nature of
work that are occurring in the United States. This phenomenon may be
affecting the health of workers, particularly those with lower socioeconomic
status (SES) (Deaton, 2003; Gabriel and Liimatainen, 2000; Landsbergis,
2003; Singh and Siahpush, 2002; Tuchsen and Endahl, 1999; Subramanian,
Blakely, and Kawachi, 2003). A report of the National Research Council
(1999) describes features of the changing nature of work such as organiza-
tional restructuring, downsizing, declines in unionization, flatter organiza-
tional hierarchies, increasing job insecurity and instability, teamwork, and
nonstandard work arrangements. The report noted that these changes ap-
pear to lead to decreased employee morale, but the report did not examine
health and safety effects of the changing nature of work. While initially
developed in manufacturing, new forms of work organization are increas-
ingly seen in other sectors of the economy (Landsbergis, 2003; Landsbergis,
Cahill, and Schnall, 1999; “The Tokyo Declaration,” 1998). These trends
have been described by NIOSH (National Institute for Occupational Safety
and Health, 2002) and are summarized in “The Tokyo Declaration,” a
1998 consensus document produced by occupational health experts from

62 HEALTH AND SAFETY NEEDS OF OLDER WORKERS
the European Union, Japan, and the United States. Research is needed to
determine to what extent and how these changes in work organization
affect the health and safety of older workers. For further information, see
the website: http://www.workhealth.org/news/tokyo.html.
Trends in Work Hours
Average weekly and annual hours worked fell for many decades in the
United States through the early 1970s, but they have largely stabilized since
then. However, the proportion of women who work for pay and who are
employed in year-round jobs has continued to rise (Rones, Ilg, and Gardner,
1997). Between 1976 and 1993, total annual hours for men increased by
5.5 percent and for women by 18.0 percent. After age adjustment, these
increases were 3.4 percent and 14.9 percent, respectively (Rones et al.,
1997). Between 1979 and 2000, for married couple families with children,
with heads of household aged 25–54, total annual hours increased by 11.6
percent (Mishel et al., 2003).
It is certainly true that employed Americans are engaged in paid work
for more hours each year than is the case in most other industrialized
countries. Only workers in Japan are typically employed for approximately
as many hours as Americans, and the average work week and work year in
Japan have recently been falling. International Labour Office (ILO) statis-
tics suggest that Americans now have a longer work year than workers in
other rich countries (ILO, 2001). For example, employed Americans work
about 200–400 more hours (or 5–10 more weeks) per year than workers in
France, Germany, Sweden, or Denmark (OECD, 2002). The growing gap
between typical hours in the United States and in other rich countries is
mainly the result of declining average hours in the rest of the world. While
greatly excessive working hours have been associated with adverse health
outcomes, it is not known how many hours are too many. A better under-
standing of the age-specific effects of working hours over short (weekly)
and long (annual) intervals will require better information on trends in
different patterns of working hours by age, gender, race, and socioeconomic
status.
The trends in employment rates and in weekly hours at work among
older Americans are displayed in Table 3-2. The top panel in the table
shows hours and employment trends among adults of both sexes. Columns
1 and 4 show average weekly hours among employed persons who reported
working at least one hour per week in March 1979 and March 2001,
respectively. Columns 2 and 5 show the percentages of all adults in each age
category who worked at least one hour per week; columns 3 and 6 show the
actual percentages holding a job. (Because of vacations or sickness, some

employed people did not work during the survey week.) Columns 7 and 8
show the change in weekly hours and the change in the fraction of people
who were employed between 1979 and 2001. The top panel in the table
shows little consistent trend in the average weekly number of hours worked
by older Americans, except among workers past the age of 65, where there
is a consistent pattern of increase in weekly hours. However, the proportion
of older Americans in employment has increased noticeably, particularly
for adults between ages 45 and 59. As shown in the bottom two panels of
Table 3-2, the rise in employment was driven by a substantial increase in
the fraction of older women who work, which more than offset a smaller
decline in employment among 45- to 64-year-old men. Moreover, the aver-
age work week of employed women also rose, fueled by a decline in the
proportion of working women who are employed on part-time schedules.
The most significant trend revealed in Table 3-2 is the marked convergence
of men’s and women’s life-cycle pattern of labor supply. American women
are now far more likely to hold jobs through the traditional job-leaving age
than they were in 1979. In contrast, male employment rates have modestly
declined. While average weekly hours have been stable, between 1976 and
1993, an increasing proportion of men (from 14.7 percent to 20.6 percent),
age 55 or older, were working long work weeks (49 hours or more). For
older working women, the proportion increased from 4.9 percent to 7.9
percent (Rones et al., 1997). Whether this trend is continuing needs to be
determined.
Trends in Job Characteristics
Workers in developed countries have experienced substantial changes
in psychosocial job characteristics over the past generation. In Europe,
surveys indicate increases in time constraints (i.e., time pressures or work-
load demands) between 1977 and 2000 (European Foundation, 2000).
Similarly, in the United States, increases between 1977 and 1997 were
reported for “working very fast” (from 55 percent to 68 percent) and
“never enough time to get everything done on my job” (from 40 percent to
60 percent) (Bond, Galinsky, and Swanberg, 1997). U.S. findings are based
on the 1977 Quality of Employment Surveys (Quinn and Staines, 1979)
and the 1997 National Surveys of the Changing Workforce (Bond, Galinsky,
and Swanburg, 1998). Somewhat increased job decision latitude or job
control was also reported in these surveys. In Europe, the proportion of
workers reporting a measure of autonomy over their pace of work increased
from 64 percent in 1991 to 72 percent in 1996 (Walters, 1998). In the
United States, “freedom to decide what I do on my job” increased from 56
percent in 1977 to 74 percent in 1997 and “my job lets me use my skills and

abilities” increased from 77 percent in 1977 to 92 percent in 1997 (Bond et
al., 1997).1
A combination of high job demands and low job control has been
called job strain or high-strain work—an important risk factor for hyper-
tension and cardiovascular disease (Schnall et al., 2000), a common cause
of disability among older workers (Ilmarinen, 1997). In theory, since job
control appears to buffer or moderate the effects of job demands on risk of
stress-related illness or disorder, increases in job control reported in the
European and U.S. surveys might compensate for the increases in job
demands. On the other hand, there may be a limit to the buffering effects of
job control. Job strain was not analyzed in the U.S. surveys. In Europe,
increases in autonomy were not sufficient to compensate for increased
work intensity. The proportion of high-strain jobs in Europe increased
from about 25 percent in 1991 to about 30 percent in 1996 (European
Foundation, 1997).
European Foundation surveys in 2000 show continuing increases in
work intensity and job demands (working at very high speed and to tight
deadlines); however, increases in job control or autonomy before 1995
have leveled off or are declining slightly (Paoli and Merllié, 2001). This
suggests that the prevalence of job strain has continued to increase in
Europe, a trend with the potential effect of increasing risk of hypertension
and heart disease.
These trends may also vary by social class, although very little data are
available to test this hypothesis. Analyses of national Swedish surveys that
combine questions on hectic and monotonous work, as a proxy measure for
high-demand, low-control work or job strain, show only a slight increase,
from about 9 percent to 11 percent, between 1992 and 2000 for all work-
ers. During 1992, the Swedish economy experienced a major recession.
Between 1992 and 2000, among low-income and blue-collar workers,
prevalence of hectic or monotonous work increased to a much greater
degree, from about 12 to 20 percent (Vogel, 2002). Unfortunately, there are
few data available on trends in job characteristics by age group in Europe
or the United States.
1A number of limitations of the 1997 Work and Families Institute Survey suggest that it
may underestimate the increase in job strain since 1977. First, the survey excluded anyone
who did not have a phone, and the response rate was much lower than the 1977 survey. Only
three demands and six decision latitude items were available, not the full Job Content Ques-
tionnaire (Karasek et al., 1998). More importantly, the 1977–1997 comparison data file
excluded self-employed, contract, or contingent workers—it included only wage and salary
workers. The self-employed contingent group was larger in 1997 than 1977. That group was
also more likely to have job strain, leading to underestimates of increases in job strain. In
addition, today, there are many more undocumented immigrant workers in the United States
doing hazardous, high-strain work, a group not likely to have participated in the surveys.

THE LABOR MARKET AND THE CHANGING NATURE OF WORK
The negative effect of increases in job strain have not been reflected in
measures of injuries and illnesses or disorders in the workplace calculated
each year by the BLS (see Chapter 6) or by measures of impairment or
function in more general datasets that are used to track heath outcomes of
older Americans (Manton, Corder, and Stallard, 1993, 1997; Crimmins,
Reynolds, and Saito, 1999). Also, they have not been sufficient to offset the
factors that are improving age-constant mortality rates, such as improve-
ments in medical care, increasing income for many groups, and exportation
of hazardous industries. However, BLS data greatly underestimates the
extent of work-related illnesses or disorders (National Research Council,
1987; Landrigan and Baker, 1991; Biddle et al., 1998; Rosenman et al.,
2000). In addition, as noted in Chapter 6, the extent of underreporting
injuries and illnesses or disorders may be increasing (Conway and Svenson,
1998; Azaroff and Levenstein, 2002). Analysis of data on impairment of
function is only currently available through 1994. Therefore, it is unclear to
what degree the negative trends in job characteristics and work organiza-
tion discussed are offset by improvements in other risk factors, both within
and outside the workplace, which may even be leading to reductions in
overall rates of injuries and illnesses or disorders. Since stress-related chronic
diseases such as cardiovascular disease and hypertension take years to
develop, it will be necessary to improve existing data systems in order to
provide valid data on trends in work-related injuries and illnesses or dis-
orders.
Development of New Systems of Work Organization
Paralleling these trends in work hours and job characteristics, new
systems of work organization have been introduced by employers through-
out the industrialized world to improve productivity, product quality, and
profitability. Such efforts have taken a variety of forms and names, includ-
ing lean production, total quality management (TQM), team concept, cellu-
lar or modular manufacturing, reengineering, high-performance work or-
ganizations, and patient-focused care (Landsbergis, 2003; Landsbergis et
al., 1999). These new systems have been presented as reforms of Taylorism
and the traditional assembly-line approach to job design (Womack, Jones,
and Roos, 1990). About half of U.S. manufacturing facilities use some
innovative work practice, such as job rotation, work teams, quality circles
(QCs), or TQM (Osterman, 1994).
Manufacturing

to economic growth, they are likely to contain features that increase job

stress and that may affect worker health. Lean production combines diverse
elements of Japanese production management (Babson, 1995); it is an at-
tempt to reduce impediments to the smooth flow of production through
continuous improvement in productivity and quality, just-in-time (JIT) in-
ventory systems, and elimination of wasted time and motion (Appelbaum
and Batt, 1994). Small teams of hourly workers, or quality circles (QCs),
meet to solve quality and productivity problems.
A 1990 report (Womack et al.) argued that in the best Japanese auto
companies, by rotating jobs and sharing responsibilities, multiskilled work-
ers can solve quality problems at their source and boost productivity; that
this results in freedom to control one’s work, which replaces the “mind-
numbing stress” of mass production; that armed with the skills they need to
control their environment, workers in a lean plant have the opportunity to
think proactively to solve workplace problems; and that this creative ten-
sion makes work humanly fulfilling. If such claims of increased worker
skills and decision-making authority are true, then such programs could
reduce job strain and stress-related illness or disorder.
Lean production provides for more job enlargement, cross training,
and problem-solving opportunities than traditional manufacturing job de-
sign (Appelbaum and Batt, 1994). However, QCs are not online autono-
mous work teams, nor are they empowered to make managerial decisions,
in contrast to self-directed or semi-autonomous work teams typical of
Scandinavian sociotechnical systems design (Appelbaum and Batt, 1994).
Lean production also leaves traditional organizational hierarchy and the
assembly line essentially unchanged (Appelbaum and Batt, 1994; Babson,
1993, 1995). Cycle time for job tasks typically remains very short (often
one minute or less in auto assembly). Mandatory procedures require that
workers follow highly standardized steps at narrowly defined tasks (Berg-
gren, Bjorkman, and Hollander, 1991; Bjorkman, 1996). Reliance is placed
on industrial engineering, time studies, and predetermined standards to
ensure maximum workloads (Adler, Goldoftas, and Levine, 1997). JIT in-
ventory systems remove the stock between operations that acts as buffers in
the system and also removes any free time the worker may have previously
enjoyed while the machine ran through its cycle (Delbridge, Turnbull, and
Wilkinson, 1993: 66), leading to more strictures on a worker’s time and
action (Klein, 1991). Thereby, workers’ personal time and flexibility become
the buffers (Delbridge and Wilkinson, 1995; Johnson, 1997; Lewchuk and
Robertson, 1996).
In Canadian and U.S. studies of lean production in auto manufactur-
ing, job demands were often reported to be elevated (Lewchuk and Robert-
son, 1996). For example, at a Michigan assembly plant, in 1991, 73 percent
of workers surveyed reported “I will likely be injured or worn out before I
retire” (Babson, 1993). British auto parts employees reported slightly less

workload if they participated in the implementation of a lean system, but a
significant increase in workload if they did not participate (Parker, Myers,
and Wall, 1995). Lean production practices may lead to reduced availabil-
ity of lighter duty jobs for older workers (Lewchuk and Robertson, 1996).
Low or decreasing decision authority was also reported in many cases,
including a decline in participation in decisionmaking and influence over
the job over time as new systems were implemented (Babson, 1993; Parker
and Sprigg, 1998; Robertson et al., 1993). The promise of producing highly
trained, multiskilled workers was also challenged by Canadian and U.S.
(Babson, 1993; Robertson et al., 1993) and British (Parker and Sprigg,
1998) survey data.
Some alternative new work systems, jointly bargained for by manage-
ment and labor, have been labeled high-performance work organizations.
However, little research has been conducted on the health and safety effects
of such systems. One example is a Michigan auto plant where 71 percent of
workers report having benefited from the team concept and, on average,
report a slight decrease in perceived stress since the program began
(Kaminski, 1996). Workers provided input to the design of the new system
before it was put in place, team leaders were elected, teams could schedule
personal and vacation time, the union monitored overtime and seniority
rights, and the new system was written into contract language and ratified
overwhelmingly (Kaminski, 1996).
In the U.S. garment industry, the traditional (and still widely used)
production process is the bundle system (Bailey, 1993; Berg et al., 1996).
Inventories are stored in bundles of about 30 cut garment parts each.
Operators perform one task, such as sewing a hem, on each piece in the
bundle, which often takes only a few seconds (Bailey, 1993; Batt and
Appelbaum, 1995). The fragmented, repetitive work combined with piece-
rate payment leads to high rates of work-related musculoskeletal disorders
(WRMDs) (Brisson et al., 1989; Punnett et al., 1985; Schibye et al., 1995).
In a new work system known as modular manufacturing, teams of multi-
skilled operators assemble an entire garment with reduced supervision and
are involved in quality control, machine maintenance, and sometimes in
setting and meeting group goals (Bailey, 1993). Piece-rate wages are replaced
by an hourly wage with a group bonus (Berg et al., 1996). Modular workers
reported greater skill use, but also increased perceived stress and no differ-
ence in job satisfaction compared to bundle workers (Berg et al., 1996).
Worker teams or job redesign (to create more task identity and significance)
were significantly associated with satisfaction; however, increased workload
or stress or both were associated with reduced satisfaction. There was no
net gain in satisfaction for modular workers (Batt and Appelbaum, 1995).
Notably, 38 percent of textile sewing machine operators are 45 years of age
or older, greater than the average of 34 percent for all jobs (Dohm, 2000).

Similar new work systems have also been implemented outside of manufac-
turing in industries such as telecommunications and health care.
Telecommunications
Little effect of self-managed teams on unionized customer service work
has been found. However, unionized installation and repair workers re-
ported significantly more job satisfaction, autonomy, coworker support,
days of training, and advancement opportunities relative to workers in
traditionally managed, highly skilled craft jobs. Their job satisfaction was
significantly associated with online participation (e.g., greater autonomy)
but not with offline participation (e.g., quality of work life, TQM, prob-
lem-solving teams) (Batt and Appelbaum, 1995). Forty-nine percent of tele-
phone installers and repairers are 45 years of age or older, greater than the
average of 34 percent for all jobs (Dohm, 2000).
Health Care Industry
In the U.S. health care industry, two forms of work restructuring intro-
duced in the 1990s have been studied. First, patient-focused care, based on
TQM, uses cross-trained multiskilled teams, with fewer individual job cat-
egories, decentralized ancillary services, and computers to reduce case
recording time. Registered nurses (RNs) manage teams, but fewer RNs are
needed because lower paid, unlicensed generic health care workers under-
take some direct care (Richardson, 1994; Sochalski, Aiken, and Fagin,
1997). Second, operations improvement seeks rapid cost savings by reduc-
ing the number of RNs and replacing them with nurses’ aides (Greiner,
1995). These two new approaches are replacing a system developed in
1970s, known as primary nursing (Brannon, 1996), professional nurse prac-
tice models, or magnet hospitals. These older models featured RN autonomy
and control over clinical practice and decentralized decisionmaking (Aiken,
Sloane, and Klocinski, 1997; Kramer and Schmalenberg, 1988; McClure et
al., 1983). Cost containment efforts have led to longer hours of work and
increased stress among nurses and have contributed to a nursing shortage
(Joint Commission on Accreditation of Healthcare Organizations, 2002).
Thirty-nine percent of registered nurses are 45 years of age or older, greater
than the average of 34 percent for all jobs (Dohm, 2000).
As discussed above, it is unclear to what degree the increased health
and safety risks associated with some new systems of work organization
(further detailed in Chapter 6) will affect more general trends in health and
safety in the workplace or in the overall (nonmortality-based) health of
Americans. Current data are insufficient for us to know if the specific
negative outcomes are of sufficient importance in the general economy to

significantly affect overall (nonmortality) injury and illness or disorder
trends.
Monitoring Job Conditions
Several decades ago the U.S. Department of Labor sponsored the Qual-
ity of Employment Survey (QES), which used a nationally representative
sample of the workforce to characterize and track features of work. NIOSH
added a module to these surveys in 1977 to assess job stress (Murphy,
2002). The surveys offered a unique resource for policy and for research.
For example, Karasek et al. (1998) used the survey instrument and findings
to develop the Job Content Questionnaire, an instrument that has gained
international acceptance as a primary tool used to measure job demands,
job decision-making authority, job skill use, and supervisor and coworker
social support (Karasek et al., 1998). The availability of a tool to character-
ize these risk factors has led to a large body of research studying the
association between work and cardiovascular disease as well as other dis-
ease endpoints, as discussed above and in Chapter 5. Although there have
been a number of dramatic changes in the workplace since 1977, the De-
partment of Labor has not sponsored nationally representative surveys
since that time. Consequently changes in organizational practices and pro-
duction technologies as well as changes in the structure and composition of
jobs held by a more gender-balanced and multicultural workforce are not
reflected in data available to understand the modern workforce.
In contrast, the European Foundation began carrying out a related
survey of working conditions in 12 European nations beginning in 1990
using a prototype survey with only 20 questions. After the pilot survey, the
survey was expanded to over 80 questions; it has been repeated every five
years, with 15,800 workers surveyed in January 1996 and 21,700 in 2000
(Paoli, 1997; Paoli and Merllié, 2001). This is a questionnaire-based sur-
vey, involving face-to-face interviews conducted outside the workplace.
The survey permits evaluation of time trends and working conditions that
are standardized for a wide variety of workplaces and different cultures. As
a result, a number of reports on trends for working condition factors have
been published. Groups of factors affecting working conditions include
physical environment of the workplace; organization of work; social and
psychosocial environment; management of human resources; and labor
law, collective agreements, and systems of industrial relations. As an ex-
ample of the survey findings, the European Foundation is able to report
(http://www. Eurofound.ie/working/working_knowledge.htm):
that problems related to health, the pace of work and working time con-
tinue to rise in European workplaces. One main conclusion of the survey
is that the phenomenon of work intensification has become an established

reality for European Union workers over the last decade. Employees may
be working somewhat shorter hours but their pace of work has increased,
in certain cases markedly. One in three workers complain of backache
related to their job. Nearly half complain of working in a painful/tiring
position while over half are working at very high speed to tight deadlines
for one quarter of their working day.
In 2000 NIOSH sponsored a limited effort to fill the long gap in knowl-
edge about the distribution of working conditions in the workforce
(Murphy, 2002). Its approach was to add a module on quality of work life
to the 2002 General Social Survey, a biannual, personal interview survey of
U.S. households conducted by the National Opinion Research Center
(NORC). A quality-of-work-life module was developed by NIOSH with
advice from a multidisciplinary panel, but space constraints limited the size
of the module to one-quarter the size of the 1977 QES. Results are still
being tabulated.
