That's the farcical part of it. You are getting payed to get X done. Then can you go home after you do X if you did in 30 hours? Can you just tell your boss: you tasked me with doing X, it is done. I am taking a half Thursday and Friday off?

Of course not. That will be met with a look of disbelief and shock. They will probably quickly assign your another thing Y that takes another 40 hours to complete so now you have 10 hours to complete the new 40 hour job.

Because there is no payed overtime everyone is relying bonuses. And guess what happens with bonuses? "Sorry this was a tough year so we had to reduce bonuses this year, but thanks for your great work".
