hi!! i JUST started at starbucks about a month ago and on my very first day of training, my GM asked me to come in 3 hours early for my next training shift- and wouldn't let me go home early. i have a brain malformation that SERIOUSLY affects my short term memory, so when these things happen im really not good at keeping up with them.

when i was openly frustrated with the sudden change in schedule(from coming in at 9:30 to coming in at 6), she asked me if i wanted to work there, obviously threatening my job. she did the same thing the next day, berated me for being frustrated, and praised the girl i was training with for getting there 5, 10 minutes early when i had been getting to the store at LEAST 20 minutes early every shift. she's been constantly telling me im doing everything wrong when she didn't even take the time to train me- all of her attention was put on the other girl and i was completely ignored and told to *stay out of the way.*

now that im actually working, she only schedules me about 20 hours a week, in four hour shifts so im working nearly every day but not making anywhere close to what i need to survive. i feel like i'm a good worker, but every time i see her she finds something wrong with me or the way i'm working. obviously none of this is okay, and i want to say something to corporate, but she's so far up our RM's ass that she covered for him for about a week and im scared it will just get back to her and i'll get punished for complaining.

should i just quit? should i try to go over our RM's head and talk to someone else? i'm just very confused and really upset, any advice would be appreciated.
