Teamsters Local 118 has agreed to put its Wegmans Food Markets [3] contract to another union vote, reports said Wednesday.

The union, which represents more than 900 warehouse workers and truck drivers, has twice voted to reject contract offers from the retailer, reportedly over concerns about proposed changes in a pension plan.

The Buffalo News Wednesday said that Wegmans and the Teamsters met with a federal mediator earlier this week, and that Teamsters were expected to vote again on Thursday.
