Pressure is on GM, UAW as workers wager striking during contract negotiations

As the clock rolls to 11:59pm on Saturday night, the first sign of a strike between the UAW and GM may come with cleaning crews walking off the job first. The automaker has a contract with Aramark to manage five GM sites, three of them in Flint and the GM Tech Center in Warren. Aamraks contract expires at the same time as the UAW contract does.
