McDonald's Corp. has warned federal regulators that it could drop its health insurance plan for nearly 30,000 hourly restaurant workers unless regulators waive a new requirement of the U.S. health overhaul. The move is one of the clearest indications that new rules may disrupt workers' health plans as the law ripples through the real world. Trade groups representing restaurants and retailers say low-wage employers might halt their coverage if the government doesn't loosen a requirement for "mini-med" plans, which offer limited benefits to some 1.4 million Americans.
