One of my last jobs before Blessed Retirement was as the Assistant Maintenance Manager at a cannery.
One guy on the crew was a middlin' good maintenance man but a HUGE pain in the butt as a (alleged) human being. Grouchy, argumentative, couldn't get along with anyone, looked on every job assignment as a personal insult, file a grievance with HR if you looked at him wrong. We called him "Triple R"...among other things.
The entire crew, including me, worked an on-call rotation. You spent a week with a pager and were on call 24/7. Calls in the middle of the night because some bonehead on the cleanup crew had run into a water line with a forklift were not uncommon. Calls at 0h-dark-thirty because the boilers were out were also frequent.
One week, RRR was on call and got a call that the boilers were out. Instead of saddling up and dealing with it, he called ME because "you only live 5 minutes away". (He lived about a half-hour away).
"Yup," sez I, "but I'm not on call, you are. Deal with it."
After calling me everything but a human being, he slammed the phone down. Seeing as I didn't get further calls that evening, I assumed he'd gone in and re-lit the boilers.
Went to work the next morning and went out to the shop as usual. RRR's toolbox was gone. Talked to one of the night cleanup crew guys and he said RRR had showed up with smoke coming out his ears, re-lit the boilers, grabbed a forklift and dumped his toolbox in the back of his truck and peeled rubber leaving.
Had I known it was that easy to get rid of him (firing him would have been nearly impossible given his predilection for HR complaints) I'd have done it months earlier...
