My coach is getting on my nerves

I just became TL maybe 2 months ago. About a month in, I had to schedule to get my wisdom teeth out (which I had been warning him would happen 6+ months ago). I asked him when i should schedule knowing he’s going on a vacation but unsure of the days. He just never responded. So I booked the closest one I could to get it over and done with before academy. Lo and behold….. it was the same weekend he went on vacation. He didn’t like that.

About 8 days after my wisdom teeth, I hit my head really hard at work, had to fill out incident report and go to ER where they told me I have a mild concussion. Throughout all of this, he never ONCE asked me if I was okay. Today is my first day back to work and he essentially is acting like he hates me.

I can’t tell if it’s because of me or because we are having a shitty day (too many picks, way too understaffed due to HIS scheduling) but his attitude is complete garbage. He’s made 2 of my associates cry (including me when I was associate) due to his lack of emotional stability/maturity. I tried to go to my SM about this but it essentially was like a “oh you know he’s stressed blah blah blah”

I’m just so over it. There’s no way to make him happy ever. We could have almost perfect stats and he would say “but we aren’t #1 in our market!”

All of my associates come to me complaining about him and I don’t even know what to do. My coach is a great person, just not a great coach and I don’t want to go to ethics over it and unsure if I can bc the things he says aren’t even harassing or offensive…. They are just flat out rude (and he’s a yeller).

Do I really just need to keep putting up with this until I finish school and gtfo of Wally??

God I don’t want to clock back in after my lunch.
