Teamster locals' `no' votes throw wrench into UPS' contract implementation - Freightwaves UPS Inc. employees at several Teamsters union locals have soundly rejected their respective riders and supplements to a five-year collective bargaining agreement which was ratified in October despite the majority of voters rejecting the contract. The actions by the locals means that the contract, which was to be implemented retroactive to July 31, 2018, will not go into effect for an undetermined period. Under rules governing the UPS-Teamsters contractual relationship, the master contract cannot be implemented until all locals ratify their respective supplements and riders. The rejections also set the stage for Teamster leadership to impose the contract on all locals if the side agreements are not ratified at the various locals. The international union took such a step in 2014 after several locals voted to reject their supplements, delaying the implementation process for months beyond the ratification date the year before.
