Zehrs and Real Canadian Superstore workers voting on a new tentative deal today.
Voting started at 10 a.m. for members with UFCW Locals 175 and 633. A second vote is scheduled for 7 p.m.
About 1600 employees from various store locations in Windsor, Leamington, Kingsville, Chatham and Sarnia will either approved or reject the contract.
A majority of them rejected a six-year tentative deal last month and walked off the job on July 2.
Picketing is expected to continue at all locations until ratification.
