Clique-y and bullying - Sales Assistant bei NEXT: Mitarbeiterbewertung

Managers were clique-y and bullies. Worked there for 3 years and got shouted at, accused of doing things. The people that worked there longer obviously got along with the managers but ever since I started, everything I did was wrong (apparently not wrong enough for them to fire me though?) Collegues would sit and chat for over 10 minutes and if I spoke to someone for 10 seconds, I was pulled up for it. Got told what to wear for my uniform (bright red jeans and a swan pattern blouse) which was clearly making a joke out of me (it was my first week there) and when I left the room I heard all the managers burst out laughing. Another time I ate a mini mars bar in the stock room whilst walking through (hadn’t ate all day and didn’t have a long enough shift to have a break, my stomach was getting a bit sore and it was all I had on me) and got pulled up and made to sign a formal warning sheet incase I “stole it” from the shop (They don’t even sell mars bars?). Just picked on constantly for the 3 years I worked there, went home in tears most days and it had a big toll on my mental health.
