Dec 15 (Reuters) -

Teamster members working at Marathon Petroleum's ( MPC )

Detroit refinery have voted to ratify a seven-year collective

bargaining agreement, three months after workers walked off the

job, the union said on Sunday, in a post on X.

Over 200 Teamsters at Marathon's Detroit refinery had called

for the strike on Sept. 4 after months of pay and safety-related

negotiations and mediations with the refiner yielded no results.

The prior contract expired in January 2024.

Marathon Petroleum ( MPC ) could not be immediately reached for

comment outside business hours.

Marathon representatives and the Teamsters had several

negotiating sessions under a federal mediator since workers went

on strike.

The 140,000 barrel-per-day (bpd) Detroit refinery is one

of Marathon's 13 refineries with approximately 2.9 million bpd

of crude oil refining capacity.
