Thanks for the excellent link. Union contract: 2,215 pages!
Long, long ago, some of my high school acquaintences went to work for American Motors in Milwaukee. They bragged about how they could drink all night and sleep in the bathrooms at the plant all day and management couldn’t touch them. Their shop steward protected them.
So this is what we have with the auto unions. But there is no American Motors any longer.
That can be a double edged sword for the union.
The one line that I bet is missing.....
"The company retains exclusive right to manage its business."
This is the most important line that management can point to in consolidating the job classifications. However, in general it is not the production guys who are the most troublesome. It's the trades, plumber, carpenter, electrician, machine repair, millwright.
The trades work 40 hours during the week and then work mountains of O/T on the weekends and holidays doing PM and fixing repairs that were cobbled to keep the line running.
