If I were you I’d confront him directly. Whether it’s in front of others or just one on one. Next time you see him and he’s sitting down or on a break just directly confront him. Be calm and have examples ready in your head. If he tries to brush you off or downplay it, don’t let him. Be persistent and ask for an explanation. I’d inform him that you’ve already gone to your manager and if his attitude doesn’t change, you’ll keep making complaints about him. I urge you to not transfer though, bc it’s rewarding bad behavior. If he is going to act like a jerk then he should get treated like one too. If he messes up a drink again? Confront him and be serious about it. If he’s going to pretend he’s so much better than you, he should actually be better and do his job correctly. You can stick this out. Do you fill out those shift surveys in your email? Complain about him there too.

I know it’s hard and you shouldn’t have to do this but this will happen more than once bc people are jerks. Even if you transfer it could be the same situation at a different store. This will make you a better person! You will never regret standing up for yourself!

Im so sorry that happened to you!! You should call partner resources on that store after you transfer!!

This situation is, first and foremost, heartbreaking. Nobody should have to work under this condition. I would also say that unfortunately, this type of situation is rampant in this industry - retail or food service. Both the partner acting immature and the SM who protects this partner at all costs. Do confront them because like u/alh1st said, backing from them is rewarding bad behaviors. I also want to present the option that whether the confrontation is worth your mental stress with everything that is going on. Is this a fight that you can see following through to the very end or simply just walk away?

I am so sorry this is happening to you, and forcing you out of your store. It’s not fair to you to be treated like that constantly, or anyone else in your store for that matter! I love to make a friendly and inviting environment at my store, making everyone laugh and having a good time.

It makes me so sad to see how other stores (even in my own district) don’t have a feeling of friends between coworkers. It’s a stressful job for almost everyone (if not all) so making the job fun and as stress free as possible between partners! I’m so sorry, but I agree on calling partner resources if your SM does nothing. Even go to your DM if possible!
