So, my step daughter worked for a local pizza joint for the last 6 months for $11/hour. She found a new gig and that company asked her to start asap. After going back and forth about whether to give two weeks or not, she decided to quit without a notice due to the fact that the employees were treated so poorly by the manager. She wasn't scheduled to work for almost a week, so there would be plenty of time for her manager to find someone to cover her shifts.
When she informed her manager (a 30+ year old woman) she immediately began berating her about how unprofessional she was for not giving notice. Using emojis. Over snapchat. She went to school this morning and a friend who was on a group chat with this manager and coworkers showed her some messages from this manager, referring to her as a “little snot” and that “she can go fuck herself”. Needless to say, she's pretty upset by the fact that a 30 year old woman is belittling her to her friends. My question is, how do I as a parent handle this? Any suggestions would be greatly appreciated.
