I have worked extra hours on salary, because on salary I’m being paid for the work, not the time. If I didn’t complete the work, I need to keep working. But that’s the fault of my own time management or inability to foresee the complexity of the task or estimate it’s workload properly.
Hourly gigs for me are always time constrained. You tell me my weekly shift before I sign and I tell you under what circumstances I’ll work OT (including rate, advanced notice, etc.) otherwise we have no deal.
I understand that not everyone is presented with the same choice or available opportunities, and my heart goes out to them.
