Anyways after the side-track, I'm Part 91, so I have no duty regs to protect me.
I work 8-4:30 M-F. I do work after those hours, and in January I worked 3 of 4 weekends. That isn't what I usually do, maybe one weekend a month if that, but we had a busy sales month and 5 trips to FL and back from IN/OH/MI area for people getting training in their new planes. My longest actual day of work was when I flew a DA40(I hate these for this reason) from MIE to CHD via IND-CPS-TUL-AMA-ELP(1500nm-ish I think). 13.4 hours in the plane, not counting fuel/food stops, but I got it out there and was home by noon the next day, with minimal sleep albiet, but I was home.
My company really tries to keep us in regular hours, but it's a give and take. If we work late or extra, it's no problem to not come in until noon the next day or take another day off etc....
Sometimes working Harder is working Smarter
