About 200 workers at the Marathon Petroleum refinery in St. Paul Park are on strike after overwhelmingly rejecting a contract they say would lead to a loss of union jobs.
A three-year contract between Teamsters Local 120 and Marathon expired Dec. 31, though union and management kept negotiating in January.
On Thursday, the union voted 167-4 to reject the company's "last offer," said Scott Kroona, a business agent for Local 120. Workers went on strike following the vote.
"Marathon basically wants to gut the contract," Kroona said. "The biggest problem is the subcontracting of jobs. Marathon wants to subcontract good union jobs to outstate contractors whose workers are clearly less skilled and qualified."
The outsourcing would lead to 40 job losses for Teamsters in both maintenance and production positions, Kroona said.
The refinery, the prime gasoline supplier to Speedway stations in the Twin Cities, is continuing to operate.
"We safely assumed operation of the refinery with trained and qualified personnel," Marathon said in a statement. "We do not anticipate supply disruptions in Minnesota or the Midwest region, including at our Speedway stations, and we expect to continue meeting all of our customer commitments."
The company declined to comment on subcontracting issues.
