Dollar General complaint: Store Manager

The store manager has demoted me for no reason,,I was on my off day came back in the next shift and she had done this no write up , no verbal communication or anything,,secondly,,she started taking all my hours away and started giving them to people she like and want,,thirdly,,I had put in 20.75 hours ,,before I was unpredictably demoted to a regular sale associate,,but when I got paid this week it wasn’t as a key Holder but as a associate,,all of this is actions of a lawsuit,,she needs to be fired ,or demoted,,,she cant keep workers bcuz of her attitude and aggressive approach,, I work full time and I’m barely getting 5 hours a week,,ACLU Labor Law will get also a wind of this bcuz of the hours situation I wasn’t properly paid for,,she is abusing her title and her position,,,if nothing is done about this store manager at store number 06598,,my next step will be taking the procedure to get a lawyer and file a discrimination and lost wages
