Subway complaint: Controlling

I was recently fired from my subway of almost 5 years. Being the manager(dean) did not like me very much, it’s not surprising to anyone. You see, me and the manager were both assistant managers last year, so when our manager at the time got promoted, so did dean. And that meant kinda having to deal with me as his assistant. Well after months of trying to get along. After countless times of bickering back and forth about anything, right after I was showing improvement on what we had agreed upon, he took his opportunity and fired me. Just like that. In the middle of this pandemic. I’ve known dean on a personal level for almost 5 years and for him to know that I’m struggling a bit in my personal life, is just cold. He’s a controlling, manipulative ahole that got handed the title manager and took it over board. Ask ANYBODY that has worked at that store. I’m not saying he’s in the wrong entirely because ya know, being on time comes with ANY job. But to literally dangle my job in my face and use that to get his way is just messed up.
