A report by McKinsey & Co. has found that 30% of employers are likely to stop offering workers health insurance after the bulk of the Obama administration's health overhaul takes effect in 2014. The findings come as a growing number of employers are seeking waivers from an early provision in the overhaul that requires them to enrich their benefits this year. At the end of April, the administration had granted 1,372 employers, unions and insurance companies one-year exemptions from the law's requirement that they not cap annual benefit payouts below $750,000 per person a year. But the law doesn't allow for such waivers starting in 2014, leaving all those entities—and other employers whose plans don't meet a slate of new requirements—to change their offerings or drop coverage. Previous research has suggested the number of employers who opt to drop coverage altogether in 2014 would be minimal.
