In Madison, the School District and School Board “are forcing their teachers to abide by — and taxpayers to pay for — an illegal labor contract with terms violating Act 10 based upon unlawful collective bargaining with Madison Teachers, Inc.,” a statement from WILL said.

Blaska, a former member of the Dane County Board who blogs for InBusiness, said in addition to believing the contracts are illegal, he wanted to sue MTI because of its behavior, which he called coercive and bullyish.

“I truly believe that there’s a better model out there if the school board would grab for it,” Blaska said.

MTI executive director John Matthews said it’s not surprising the suit was filed on behalf of Blaska “given his hostile attacks on MTI over the past several years.”

“WILL certainly has the right to challenge the contracts, but I see (it as) such as a waste of money and unnecessary stress on district employees and the community,” said Matthews, adding that negotiating the contracts “was legal.”

In August, the Wisconsin Supreme Court ruled Act 10 constitutional after MTI and others had challenged its legality. At the time, union and district officials said the contracts that were negotiated before the ruling was issued were solid going forward.
