Do you have to belong to the UAW?

Being forced to join the union depends on what state the plant, buisness, etc. is located. Texas is a work at will state, and where I work anyway, union participation is not mandatory. I am not however, in the auto buisness. My uneducated guess would be the truck plant in Arlington, would not be mandatory, as IIRC in this state, an employee may not be forced to be a member of one.
