FORT WAYNE, Ind. (WOWO) — They are part of the United Auto Workers union — and they plan to hold a vote over whether or not to strike on Wednesday.

The local union in Fort Wayne says GM is violating terms of the new contract agreed to after a messy nationwide strike last year — by laying off roughly 250 temporary part-time workers whom the union was hoping to make temporary full-time workers.

A GM spokesperson says they are abiding by the terms of the agreement and that there is no legal basis for a strike.
