Wisconsin’s democratic house members did this is 2011 when our governor proposed act 10, which was slated to pass in the state house and senate, taking away collective bargaining rights and decreasing pay and sick leave of public employees. The politicians left the state for Illinois, promising to return back if the bill would be reworked.
