Okay, as a former manager:
1) your availability is what you CAN work; this means they CANNOT schedule you for times that are not listed on that paperwork
2) You are listed as full time or part time, if you are full time you MUST have the minimum amount of fedrealy mandated hours(I beleive that's 36 now); if you are part time you can work as few hours as three, but no more than 40.
3) All stores must have an open door policy when dealing with internal issues; if you are not comfortable going to internal managment you must be given the number of HR and/or your district manager.
4) All hiring must be equal opportunity/unbiased due to race and/or gender. Anything else is in violation of people's civil rights.
5) All employees are required to take one ten minute paid break for every four hours worked and one twenty minute unpaid lunch break for every five hours.


So, if your manager isn't allowign you breaks, they're violating number 5, this is a federal law. If they're 'selectively' hiring, their in violation of number 4, also a federal law. As an employee you already feel you can't deal with this internally, and must go externally. I would mention these other problems at hte same time, sounds like your manager is asking to be fired.
