Some employees will think its a good deal, the employer will give them the money for their part of the insurance, and the federal government picks up the rest of the tab.
This just happened to a friend of ours. He is retired but his wife is still working and her employer gives X amount of $ to her to help with health insurance. They had a castastrophic plan that cost $367 ( or thereabouts) a month. Got cancelled under Obamacare. Every policy they checked was waaaaaay expensive. They finally used CoveredCa to get an $1100 a mnth policy that costs them almost $400 amnth after subsidies. Their coverage for the new Obamacare policy is less than their catastrophic policy and costs almost triple the price without subsidies!!!
Wait until she retires, their costs will skyrocket.
