I just want to mention that my sister is a salaried employee and is required to work 10 hours over her 40 hours a week every week for the next 3 months. It's mandatory. 10 hours. And I guess they are holding a gun to your sisters head and are preventing her from seeking employment elsewhere. That's really, really, really mean of them.
She's looking..but the job market is so great right now...they will hire her at about half of what she is making.
