This Law Firm Publication by Ogletree, Deakins, Nash, Smoak & Stewart, P.C. addresses Wisconsin Governor Scott Walker's March 9, 2015 signing of Senate Bill 44, a right-to-work law. The law prohibits the negotiation of union security or closed shop clauses in collective bargaining agreements renewed, modified or extended on or after March 11, 2015 (the bill's effective date). Wisconsin is the 25th state to pass a right-to-work law and follows its neighboring states of Michigan and Indiana in passing the law. Wisconsin's law was fast-tracked to avoid protest and there is no extended waiting period before the law takes effect.
