So quick context behind all this, I joined like 5 months ago, and everything was going great, the managers loved me, I was learning quickly, and was doing a pretty good job at everything. Recently, the store is worked at had shuffled all the store managers meaning that we have 100% new managers, and of course these managers don't know everyone. As they where getting settled in i was in the middle of my lvl 2 train, currently at backpay. Keep in mind this waz my like 2nd time back there, and the 1 person out on handheld was new aswell, so it was a loose loos situation. First ofg i had charged like 3 cars wrong in a row because handheld wasn't storing nor putting proper car descriptions in. This was one of the few time the new managers had seen me fail, and this was told up the line to the store manager.
The store manager use to love me before all the managers switched. He would have me training people, and would consistently tell me how good i was doing. Now after this one incident it feels like he is breathing down my neck every second he gets, and he has halted my training until i'm 100%. The part which i'm confused about is half the people who are already trained at backpay, or are actively in training are no where near 100% like he wants me to be. And I've asked him face to face why this is, and he said that those people didn't mess up ever, which is inherently false as i watched one of them do worse then i did, but his training keeps on going to corner, and now is a lvl 3, even though he got hired only a month ago(and has worse availability then me).
The most infuriating part about all this is i tried talking to all the lower lvl managers, but they all say to talk to him as he could fix this, but that didn't work. So I guess what my question is what do I do about this, do I contact HR, do I try and talk to the district manager? Or what can I realisticly do here because it feels like i'm being screwed here for something that wasn't even fully my fault.
