HCR Update from Mark Sanna: Target has announced that it will no longer provide health insurance for part-time workers but will send them instead to the new health care exchanges established by the Affordable Care Act. The change could help low-income workers who will now have access to subsidized coverage. It might distress middle-income workers ineligible for a big subsidy, and it is likely to be bad news for taxpayers, who will foot the bill for the coverage Target had provided.
