"I was told I was breaching my contract..." I love it when the first response is to try intimidation!

This is exactly why I keep harping that it is WE, and no one else, who are the experts. Not the manager, not the enginer, not the man in the moon.

I can forgive an outside contractor for not knowing the machine intimately, and hooking it up. It is, however, the role of the maintenance crew to ensure that the machine is safe for operation. If the maintenence guy locks a machine out, HIS is the word tht needs listening to. If management has a problem, they know who to ask!

Safety is probably less than 25% about rules, equipment, and procedures. 75% is what we might best call "corporate culture." In simple terms, poor management leads directly to more accidents.

Sounds like the paper is best left behind. It's got the inmates running the asylum.
