No bosses in my situation aside from the customers. Your choice of "cut your legs" is interesting though, quite emotive. If an employee is paid to deliver a product, what difference does it make to them what is done with the product when they're finished with it?
Again, I could understand it if it was never coming out (especially as they'd lose their credits on the title), but obviously that's not the case here.
I guess I'm just built a little differently. I would be frustrated by the long hours, but my work in this case wouldn't be pointless. Plus I'd be expecting some well deserved time off.
