The United Auto Workers union (UAW) has reached a tentative agreement with Fiat Chrysler Automobiles (FCA) and is presenting the proposed contract to its members for a vote beginning this week. The contract affects some 40,000 unionized hourly workers.

At the beginning of the economic crisis in 2007 the UAW agreed to let Fiat Chrysler establish two tiers, that is, workers doing the same job would have different rates of pay, with newer workers sometimes working for $17 an hour while more senior workers might earn as much $28 an hour. Such a system had been introduced earlier in the auto parts plants.
