training???? (USA)

okay so i’ve been working at mcdonald’s for over a week now, & i’ve only been put on front window (handing out food) back window (cashing out) & fries. therefore i have no clue how to do absolutely anything else besides make a mcflurry or a basic iced coffee. today i worked 11-2 and there was a huge rush. i’ve worked fast food before so i wasn’t too worried until one of my coworkers starts coming over to my window to complain about how i’m not trained and i don’t know what im doing and all this bs. but like i’m honestly really good at window and everyone has told me that i am, hence why that’s all they have me doing every day. i was getting f more and more irritated bc like, if you think im so bad at this then why aren’t you trying to train me or something?? i dont know how to do headset at all and they ask me everyday if i know how to as if im just magically going to come back knowing everything. hell i don’t even know how the damn thing itself works nor do i know the layout of the menu. its really starting to piss me off bc even my MANAGER won’t help me, she just gets mad and throws me on window. idk i’ve just been big stressing and im wondering if anyone else was literally just thrown out to the wolves bc ive pretty much just had to learn as i go with everything, which im not really upset about im just mad that everyone else is acting like it’s somehow my fault that no one will help/train me. i tried talking to my manger about it but she just brushed me off, & i don’t think she has liked me from the day i started anyways. i like the job but the people honestly suck and they all just pmo every day because again, they get mad that i apparently just suck at the job but they won’t show me how to do anything. someone pls tell me you relate bc it is absolutely bugging me. they’ve also been scheduling me on all of the days i specifically said i could not come in but that’s a whole other story.
