Being a union-free workplace has many advantages, but there are also some built-in benefits to operating under a collective bargaining agreement. For one, such contracts typically require all rank-and-file employees to take their complaints to arbitration rather than filing a federal lawsuit.
Recent case: Steven Jensen worked at Calumet Carton Company. He complained that a co-worker began to harass him by showing him photos of nudes, making lewd comments and touching him. He filed a federal sexual harassment lawsuit.
The company successfully got the case moved to arbitration because the union contract stipulated that all employment disputes had to be arbitrated under the terms of the agreement. (Jensen v. Calumet Carton Company, No. 11-C-2785, ND IL, 2011)
