The range of employee benefits in the U.S. private sector has looked largely the same for the last 50 years or more. There has been a migration from retirement pensions to 401(k) and 403(b) plans, but the core packages of medical insurance, dental insurance, life insurance and disability insurance have been at the forefront for a long time. Here is some information from the U.S. Bureau of Labor Statistics regarding the number of workers having access to these most commonly available benefits:
Most U.S. employees are offered some kind of medical benefit (though there are significant differences in offerings when comparisons of full-time and part-time workers or government and private sector workers are made), and there is a modest percentage of the population offered other benefits (like the ones listed above). The universe of potential offerings has not changed measurably. The status quo may soon be disrupted.
