Chrysler's Windsor Assembly Plant will work Sunday this weekend.
The plant will run because the minivans made there are selling so well.
Tony Greco is the Unifor plant chairman at Windsor Assembly Plant. He said Sunday work is unusual, but it's an indication the product is still selling.
Enough workers have volunteered to make sure all three shifts will run.
James Stewart, a vice president with Unifor Local 444, which representing the employees, said there is a possibility the plant will run next Sunday, too.
"They're talking about some overtime then," Stewart said. "That'll be all voluntary. There's nothing forced, as per the collective agreement. Prior to the holiday season, it gives them an opportunity if they're looking for extra income."
The assembly plant has about 4,600 workers. Employees at the local supplier plants will also get overtime.
