If I ran a corporation in this environment the first thing I would do is tell all the unionized employees that as soon as their contracts end they will not be offered insurance so don’t ask, I’ll take the fine instead.
Here is a bigger irony. Many union pensions invest in the stock market. Obamacare cuts into corporate profits, which in turn will crash their stocks which in turn will crash the pension funds.
Hoe about telling them that the government intervention voids the contract and end the insurance immediately?
