Health insurance in the United States

However, in a 2007 analysis, the Employee Benefit Research Institute concluded that the availability of employment-based health benefits for active workers in the US is stable. The ``take-up rate,'' or percentage of eligible workers participating in employer-sponsored plans, has fallen somewhat, but not sharply. EBRI interviewed employers for the study, and found that others might follow if a major employer discontinued health benefits. Effective by January 1, 2014, the Patient Protection and Affordable Care Act will impose a $2000 per employee tax penalty on employers with over 50 employees who do not offer health insurance to their full-time workers. (In 2008, over 95% of employers with at least 50 employees offered health insurance.) On the other hand, public policy changes could also result in a reduction in employer support for employment-based health benefits.
