Under the Affordable Care Act, firms that employ 50 people or more must provide full-time workers with health insurance, or face thousands of dollars in penalties. California labor advocates say large companies are already cutting workers' hours to get around the Obamacare mandate. Proposed California legislation is aimed at preventing low-wage workers who lose hours - and their health care coverage - from turning to Medi-Cal, the government-funded insurance program. This bill goes further than the federal health care law in that it applies to part-time workers as well as full-time. And that could have devastating and unintended consequences for some California nonprofit businesses and family farms.
