It all depends on the LL in the area
In one area I got OT after 10 hours of casual OT, in other words they expected you to work 50 hours a week but if they asked you to work more than that they paid OT.
In another area they did equal swap for comp time only, unless it was Nov /Dec then paid OT as the rules were comp time could not be carried over.
In another area, LL6 did a forced 18 month death march (150 hour weeks) with the promise of 6 months of comptime and a large completion bonus. At the end of the project he claimed we were all liars and we all had willing worked 150 hour weeks and he had promised nothing. Of course HR and management team backed the LL6. Then the con artist gave us all scathing reviews and blocked us from moving within Ford. There was much celebration when the jerk retired in 2021.
