Legal Actions by Employer?

I have a friend who doesn't speak English who signed an agreement entitled "Independent Contractor, Non-Competition and Confidentiality Agreement." She works for a cleaning service and is not at all an independent contractor as she has to abide by hours imposed by her employer, vacations, days off, etc. He pays her $11 per hour. In this agreement he states that she will have to pay taxes on her own because she's an independent contractor. He also demanded a $1,000 deposit in the event while cleaning she would damage something and is holding that money for 80 employees who he states are independent contractors and is earning interest on that money, is that legal? His non-compete agreement states she cannot clean houses (after leaving his company) on a 50 mile radius of his business, but she cannot travel very far finding homes to clean as she now wants to leave and finds herself in a bind. Now he's making her sign additional docs in order for her to get her $1,000 back. Additionally, he told her after she gave notice that she has to work 2 more weeks to train new people otherwise she will forfeit her deposit. Can he do this?? Most of his employees do not even read or speak English.
