In the 70’and 80’s I had experience dealing with Steelworkers at a heavy industrial plant in a mid-sized corporation. Unfortunately, the three year contracts expired in the summer and these unearned vacations appealed to them for only one time did they not go on strike. We ran the plant with supervisors and office workers. Our corporate management did a good job of not bowing down to them and worked out good contracts - fair for both sides - not like the auto union negotiations.
These strikers played rough. They would use sling shots aiming ball bearings at car windows, often female employees, breaking the windows. The idea was intimidation, instead it made the gals boiling mad. Strikers would take nails and bend them into jacks, then driving along side trucks, 18 wheelers too, would throw the nail jacks under the wheels. The plant was in a rural area and many supervisors lived in the country. Sometimes they would strangely find an out building on fire in the middle of the night. This is the union way.
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.
