shtty hours

So now that ERP is gone for me (I have no clue why they took me off because it doesn’t start until May,) I’m now officially back to my store. When I was on ERP, I would get around 32 - 40 hours consistently. Now that I am back, i only get like 16 - 24 hours. I work at a tough ass promo store and I’m not trying to sound egotistical but I genuinely think I am one of the best clerks at that store! I always get praises and great feedback whenever I was on ER, literally the best at any kitchen I work at especially my store, overall well rounded clerk that can basically do assistant’s work as well but for some reason I get little hours. I dont get how they can schedule this other clerk damn near 6 days a week but I can barely get any hours. I genuinely hate this job and I’m so close to quitting. I have my resume prepped and i’m so ready to apply to new jobs. Whenever I talk about promotions to be a CT, my SM is so dismissive and doesn’t really do much about it. He hasn’t even done my 1on1 when I asked. He just paid for my time and said “it’s whatever’s” when im genuinely trying to improve and get better. My only option is to switch store or to switch jobs.
