No, what I mean is that salary guarantees you get @ least 40 hours of pay (assuming salaried full-time). If you show up for work and they send you home, as a salaried employee you still get paid. Or if you finish the alloted work for the week early, you still get paid for 40.
After all of that is when non-exempt comes into play with OT pay according to federal & state regulations and any contract guarantees that go above those regulations.
