The Democrats running for governor are pledging to end GOP Gov. Scott Walker’s union restrictions, while Walker is promising to veto any changes to Act 10 if he wins re-election and Democrats take control of the Legislature.

Act 10 — adopted amid massive protests shortly after Walker took office in 2011 — brought the governor national attention and helped fuel his brief presidential run.

The measure all but ended collective bargaining for most public workers and required them to pay at least 12% of their insurance premiums and half the contributions to their pensions. The changes saved state and local taxpayers — and cost public workers — billions of dollars.

Democrats view the law as a move by Walker to hobble organizations that have long backed Democrats in elections.

The nine Democrats seeking their party’s nomination in the Aug. 14 primary said they would seek to reverse Act 10, while Walker touted the savings it has brought to taxpayers.

“The far-left Democrats who want to undo it will open the door to massive property tax increases or reductions in school staffing — or both,” Walker spokesman Austin Altenburg said in a statement. “Scott Walker will not let that happen and will continue to support reforms that put more resources in the classroom to improve the education of our students.”

Walker would veto any attempt to change Act 10, Altenburg said.
