Ford is moving production of the Focus and C-Max out of the Michigan Assembly plant in Wayne by 2018.
The automaker isn't saying where the Focus and C-Max will go, but it's likely to be Mexico.
The industry trend is to build less profitable small cars there because of Mexico's lower labor costs.
In a statement, Ford says "We actively are pursuing future vehicle alternatives to produce at Michigan Assembly and will discuss this issue with UAW leadership as part of the upcoming negotiations."
Sales of the Focus and C-Max have dropped along with fuel prices, and Ford is currently cutting 700 jobs at Michigan Assembly.
