(Adds details on voting dates on UAW membership by

Mercedes-Benz workers)

April 17 (Reuters) - After a series of wins against the

Detroit Three automakers last fall, United Auto Workers (UAW)

President Shawn Fain is trying to use his influence to organize

other U.S. auto factories that have stayed out of the union's

ambit.

The UAW has tried and failed for years to organize non-union

U.S. auto factories, most of them built by Asian and European

automakers in southern U.S. states where so-called right-to-work

labor laws make it optional for workers to pay union dues.

Volkswagen workers in Chattanooga, Tennessee, will vote this

week, beginning Wednesday and ending on Friday, on whether to

organize with the UAW union. It would be the third time in 10

years that the union has sought to represent VW Chattanooga

workers. Winning a vote to organize the VW plant would be a

significant milestone for the UAW.

Here is a timeline of UAW's contract talks with the Detroit

Three automakers and its efforts to organize non-unionized

factories:
