It was a small-ish company at the time (>20 employees) but the owner, who detested me, pulled some shit like this. I'd been with the company since there were only 5 of us, managing all aspects of his warehouse and then some but he really couldn't understand what I brought to the company. Constant browbeating, belittling in front of other employees, assigned blame for the pettiest shit; it was kind of a nightmare that I just put up with because job options were very limited in the area.

Anyway, he was prone to just letting people go on a whim and almost did so with me after a heated disagreement about our respective philosophies on inventory management. The other two managers had to step in and stop him since no one really knew how to do my job, which led to two days of wrangling with him behind closed doors in an effort to prevent what would have led to a real mess for everyone left behind. It was almost funny imagining the two other people who basically kept the place running having to talk the idiot owner into shooting his business in the foot.

The compromise was a laundry list of demands, expectations, and retractions of "privileges" (including a recent pay increase I had fought for) in order for me to keep my job. It was super transparent and I just saved him the trouble by putting in just enough notice to write out a manual for the position and train in a packer who was interested in a promotion. If I'd stayed I reckon it would have been less than a month before he found a way to fire me "with cause".

6 months later I ran into the guy who assumed my role and took great delight in hearing that he'd been so stressed out trying to keep up that they split his duties up between him and two other people.
