The employers use is a corrupt union leadership that betrays its members.
I watched the UAW betray the employees at Delco by not allowing sign up cards to be distributed and insisted we use a circulated sign up sheet which frightened the timid into not wanting the management to view the 'suspect' union advocates.
They told us that any attempt to circulate private cards the management wouldn't have opportunity to data base, would be an abandonment of their sponsorship.
Although the hourly workers were successful in their initial self-organized union vote; when the officials of the UAW arrived to 'help' the salaried employees, they sabotaged the whole attempt. The site is now gone, no one works there. Delco Electronics no longer exists in Goleta, Ca. The facility that built the Lunar rover.
The facility that developed the HRG guidance system.
The facility that allowed GM Motorsports to win 4 years in a row at the Indy.
It employed about 2000 people.
