I have these coworkers that are always acting like high-schoolers. My work friend has become a lead. She moved to a different night. These girls plus the assistant manager were giggling and making fun of me and asked her if I moved my nights because I was trying to get away from them. And again they were laughing about it including the assistant manager. My friend was furious and didn't say anything. My mother is mad at her because she didn't stand up for me and also thinks shes not a true friend and true boss. My thoughts are when its 5-6 girls against 1 you cant do much plus shes a new lead so she cant try and ruin that. Am I in the wrong for thinking that and is my mother right
