Burger King

So I just quit a few days ago because of School. One of the employees posted a picture of the group chat of him and other managers talking behind my back on instagram. This was not the only time he was doing this, reports of other employees experiencing the same thing have happened too. The name of the man was Brian Pascual. Sonia, Sherrie, Emil are managers. I was also treated with disrespect when I had an accident. My mom made the call to tell them to get me off the schedule but proceeded with giving me a write up instead. Please resolve this, some of these people don't deserve to be treated like this.
