everything. where to start - new employees are treated like garbage. no vacation days until 6 months then you get 3 days.... for an entire year (sick/vacation). useless pto. no insurance... even though you are working for AAR they use a staffing company - which is still aar to get away with this. not paid for hours worked - manipulate hours/pay weeks in order to avoid paying OT. scummy leadership, favoritism, and unless you're related to or sleeping with someone in leadership - you will get laid off.
