I was the good employee many times, gave 2 weeks notice to companies that while I didn't hate working there there was better opportunity at the next one. Until I worked for the "Prince of Darkness" (LOL)
I had been a commercial HVAC service tech in the van, company had a great reputation, good group of guys in the field and a solid customer base. One day the owner asks me to try out doing sales ( I had previously been a marine engineer and did a stint building submarines so had a degree and some pretty good experience in project management)
Many years later I'm still not sure if others pushed him into asking me to do sales but the school of hard knocks I went through in hind site should have been a red flag. Maybe he thought I'd fall flat on my face and ask to go back to the van like several guys before me had done? We'll never know for sure but I have a pretty stubborn streak built in and failure has never been an option so in spite of circumstances with the owner I ended up doing pretty well. I will say that while he was never an easy person to work for he did pay all of us well.
Eventually he heard the siren song of people looking to buy the company and he and a couple of the senior guys got big pay days, the rest of us got to start justifying our existence to our new corporate overlords. I was in my early 40's at the time working 12 hour days not including commuting and getting progressively more burned out.
Fast forward to one evening in the office (we used to stay "late" for a meeting on Thursday nights, we often wouldn't get out of our meetings until 7:30) I stop by the owner's office to wish him a good weekend (no Fridays for the main man) and he starts screaming at me about some issue with a customer that I was supposed to have dealt with in front of all my coworkers. I'm clueless because satan has forgotten he never discussed this with me. At this point I'm considering all sorts of creative ways to murder someone but oh there would be witnesses. Many (20) years later I'm still amazed I didn't cause this individual serious bodily harm, I don't recall before or since feeling the amount of anger I felt at the time. (Yeah, time to go!)
I had vacation coming up a week or two after and I remember it being mid week at our summer place on the lake. It was a perfect summer day, the kids were jumping off the dock, my wife and I were sitting watching them and it hit me like a bolt out of the blue. I turned to my wife (who probably thought I was having a stroke) and said "why am I killing myself for this SOB, all of this is paid for, what more do we need! AKA the "Epiphany"
It's funny how life works out. The week after I got back from vacation I ran into a guy from my apprenticeship class that had started his own company. He'd tried to hire me before and when he asked this time I said that we should talk. 3 months later I quit no notice on the first work day of 2004 because the SOB held our bonus checks until Christmas Eve.
That was 20 years ago and the owner's son who worked summers when I started is now the CEO. I've been working 4 day weeks since 2018 and dropped to 3 at the start of this year. I figured I'd make less money when I left the previous company but as it turns out I likely did better financially and gained a better work / life balance. The CEO values my experience and wants me to stick around as long as I want to. Win / win.
TLDR: Take care of your family and self first. Money isn't everything but sometimes when you stand up for yourself good things happen.
