Sonic Drive-In review: manager and employee harassment and company liability on skates

My daughter job walk off the job for sonic drive-in in nederland, texas on nederland avenue (12/29) and I would like answers and to explain why. First off she was required to wear skates which was not explained to her when she hired on there. She feel two weeks ago (Week of 12/15) and really hurt her back (A customer actually helped her up, not her manager), probably caused permanent damage from her skates coming out from under her when she was trying to stop at the car she was serving. Well they took her off the schedule for about a week then when she went back they got upset with her and made her put her skates on, but no one else had to put them on that night. I would say this is harassment and also a liability to sonic for them to make them wear their skates with no option and also only make one employee do this. I want answers and I want them now! The manager on duty was named dylan and the other is megan, also there is disgruntled employee named lucinda that constantly harasses and is ugly to the younger employees. This place is very unprofessional. The manager, when my daughter decided to leave because she didn't think it was fair for her only to have to put her skates on (And was also scared to fall again), threw her paperwork at her. Very unprofessional! I have heard things about this sonic before. I think you guys need to make it optional for skates because I am telling you, someone will end up suing sonic for this. I dont want my daughter having permanent damage from being a carhop at sonic! That's ridiculous!
