Fiat Chrysler and PSA may merge, which has the potential to impact UAW contract talks. Under the current merger proposal, Fiat Chrysler would give a lot of control to PSA. The merger and associated power shift has some UAW members concerned that the firms will force American workers to compete with European workers for product allocation. However, a larger firm can also mean a competitive advantage which leads to greater benefits for workers in the long run.
