The new health care law wasn't supposed to undercut employer plans that have provided most people in the U.S. with coverage for generations.
But last week a leading manufacturer told workers their costs will jump partly because of the law. Also, a Democratic governor laid out a scheme for employers to get out of health care by shifting workers into taxpayer-subsidized insurance markets that open in 2014.
While it's too early to proclaim the demise of job-based coverage, corporate number crunchers are looking at options that could lead to major changes. Gov. Phil Bredesen, D-Tenn., said the economics of dropping coverage are "about to become very attractive to many employers, both public and private."
