Domino’s Pizza complaint: Manager complaint

I worked there for over 3 months then took a month off to have my baby. I went back to work and witness a manager harass and verbally abuse another employee in front of myself and Walmart employees and customers so I tried to call the manager over her and report it while he was outside smoking but he never contacted me back while I was on my shift. So I left. I’ve worked overtime, went in when others called out, and stayed late to close while they stand around and gossip. This new manager that did this was already involved with another manager and was always making advances in front of us which we reported and nothing was done instead she was promoted. Really?? Being rewarded for doing this. Managers are supposed to be profession and go by guidelines to refrain from harassment on the job but instead The Brewton store promotes it.
