MADISON, Wis. - Two meat-packing plant workers have failed to show that all workers in their proposed class were denied overtime in a manner similar enough for certification to be appropriate, a Wisconsin federal judge ruled July 15, denying a motion to certify their state claims and granting a motion by the defendants to decertify federal law claims that were previously granted conditional certification (Gustavo Utrera Viveros, et al. v. VPP Group, LLC, et al., No. 12-129, W.D. Wis.; 2013 U.S. Dist. LEXIS 97997).
