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.
And that's a bad thing???
