Read the full story here.  This is a small but interesting part of the story about the school districts that were previously mandated to purchase all insurance through WEA Trust, a nonprofit affiliated with the largest teachers union.  The collective-bargaining component of Walker’s plan has yielded especially large financial dividends for school districts. Before the reform, many districts’ annual union contracts required them to buy health insurance from WEA Trust, a nonprofit affiliated with the state’s largest teachers’ union. Once the reform limited collective bargaining to wage negotiations, districts could eliminate that requirement from their contracts and start bidding for health care on the open market. When the Appleton School District put its health-insurance contract up for bid, for instance, WEA Trust suddenly lowered its rates and promised to match any competitor’s price. Appleton will save $3 million during the current school year.
