My mom is being bullied at work, need advice
My mom is currently an assistant manager(AM) at a restaurant chain and I believe she is getting bullied at work by her general manager(GM) and I just want to know what would be the best way to deal with it because I am so fucking angry for her.
The bullying started when my mom was first promoted to AM and was moved to her store to work under the GM. At first, it was because my mom made mistakes in the beginning (which I believe is common for anyone new to the job). Then, the GM would yell at her for not knowing english fluently. GM would purposely make her attend meetings to help her "practice english" and then yell at her for not understanding certain things. My mom was also the only one who did not get paid hours for attending these meetings. The GM would call my mom anytime there was the smallest problem or mistake even during hours she is off work (the tone she uses just makes me want to smack that bitch fr). The GM would also threaten to demote my mom if she keeps making any mistakes.
Just to preface, my mom is a pushover and is afraid to defend herself. She also does not speak english fluently but she is extremely efficient at her job and has worked for the establishment for 10+ years. She was happily working before she became an AM and she has dealt with this for 3 years. I just can't stand that she is going through all of this and she won't do anything about it. She says after being yelled at by her GM she can't sleep well some nights. She has looked so much older recently and this situation genuinely makes me want to cry.
Is it possible/appropriate for me to help her handle this? How should she deal with this so that she won't lose her position or face any retaliation? She is afraid that her GM has good relations with admin and get her demoted if she says anything.
