The UAW is an odd example of a super multi industry union. The Resident Advisors at my university were obligated to be UAW members.
The UAW theoretically got involved in the employment contract negotiations, but none of the RAs could get in touch with them despite paying union dues. There was a group trying to organize action to leave the UAW and form an independent union.
Large organizations tend towards incompetence and corruption over a prolonged period of time.
