technological change increases the intellectual burdens to stay current, but those who take on these burdens and keep their skills up to date are usually more employable than those who have not.
Over the longer term, ongoing training could relieve tightness in IT labor markets both by reducing turnover (which causes vacancies) and by increasing supply. Fully trained workers would likely be more productive, thus reducing the rate of growth in demand for new IT workers. And with well-established ongoing training systems in place, employers could more easily hire and productively employ workers from other occupations, thus increasing the total supply of skilled IT workers.
The potential contribution of ongoing training to increasing the supply of IT workers will likely be easier to realize over the long term because in the future, the IT workforce will include a larger proportion of workers with a formal IT education. With strong foundation skills, these workers may be easier to retrain than those in the current workforce.
