Bendrr...that was a real tough one.
You did the honourable thing, and the SMART thing.
You're damn straight you not only could have lost your job over this, but it could have proved far more serious.
I have known fights to end in manslaughter (accidental death). It's not worth it.
Jerry has proven himself, that he is incapable of working with others.
You are to commended and respected for how you handled this delicate situation. It could have gotten real ugly, messy and you actually showed WHO was the real man in this situation.
If Jerry thinks life is settled at the end of a fist, or weapon: we know that the definition of LOSER, will apply to him.
I take my hat off to you Bendrr (Mike).
I too am a bit concerned about how things will turn out on Monday. I hope that your safety is paramount, and that this firecracker hot-headed jack-ass is told in no uncertain terms, to stay away from the workplace, you and your family.
If he pulls any tricks, call the police.
Be careful, be safe, and be here on Monday night to let us know how things went.
I'll be thinking about you. Really. This has my stomach in knots bud.
