I can almost guarantee she was counting "on call" time as overtime.
I did a stint in offshore O&G rig work and it was 12 on 12 off for 28 straight days in a rotation, so I was getting in 84 hour weeks for a month straight, BUT that was in a crew rotation with an entire month off to mentally and physically recover. That time was paid at 1.5 and 2.0 overtime per the law after it hit the weekly hours, so it was good pay but my base rate wasn't nearly that high to start. Working 65 or 70 hour weeks nonstop isn't happening for most people without breaks or periodic slowdowns unless their work is really low level of intensity and effort.
