Union bosses are almost all criminals, many of the members are also, but there are some decent people that are members.
I was a member of the USW when I was in College and a while they were very corrupt and lazy, the members thought they were honest and hard working.
They believed that working for 4 hours and slacking off, so that their "2nd and third shift brothers" would have some work to do was the right thing.
They never saw it as stealing or being corrupt and they always blamed everything on the "big shots".
When I graduated from college, the workers that I knew couldn't believe that I'd take a job in sales making less money than I was making with the Steel Workers at the time.
I never regretted it for a single second.
P.S. My father was a member of the USW for 40+ years, but he was one of the naive, good guys that believed all the crap that the union thugs lied about all the time.
Most all were good folks, the dirty tricks guys were also poor performers the company couldn’t terminate because of union. Interestingly, of all the first line supervisors replaced or hired, about half were from the ranks of the union, the others recent college grads. The former union members were often biased against the union, more so than the college grads.
