MADISON, Wis. — School districts throughout Wisconsin have some tough decisions to make about mandatory health care for their part-time employees.

The Affordable Care Act, or Obamacare, requires employers with more than 50 full-time workers offer Health and Human Services-approved health insurance to all employees working more than 30 hours a week.

Failure to do so could result in fines that could run into the millions of dollars for institutions that employ hundreds or thousands of workers.
