We repair electric motors, but part of the company also does construction/maintenance electrical work. We're under the IBEW and they have allowed workers to cross several picket lines at major companies here. This union is pretty much worthless, and is only there to suck up dues. They do very little for the workers.
My electricians were of a different breed. As they were subs, they pretty much had free rein. After all, ya can't cover a wall unless "Sparky's" done! Same thing with the fire sprinkler guys.
I have to say those guys got the job done! Sometimes, I didn't work as many hours as they did, but they were subs and not really under my control, other than scheduling and progress deadlines.
If they started costin' me money in penalties, shit was goin' to hit the fan! I can only recall a few times they ever had to be leaned on, and ended up bustin' their ass in order to get their shit done on time!
Carpenters, welders, and laborers on the other hand...............
