If I want to live in a particularly desirable house, I have to earn more money than the other people who want to live there too, so I can outbid them. So I'll work harder than them to do so.
(Trivial concocted example for illustration purposes, not meant to be nitpicked)
I'm not saying overtime is not allowed, but if it's expected to be the norm then it very much must be in the contract. If the overtime is not a regular expectation then it must be compensated appropriately, and even then there are upper limits to the amount of overtime.
People used to be able to sell themselves/their children into slavery and business people were just fine with it. Then we made them feel shame to treat humans that way. Then we made them feel shame for employing little kids. Them we made them feel shame for threatening a person's ability to provide for their family as leverage to dictate. As soon as they could, they backslid on the last one. Certain states are repealing their child work laws.
This is not normal. This is not how the US was the majority of my life.
This contradicts what you already said ("there are always more TODOs"). Which one should I reply to?
If your employment has fixed deadlines, and your employer does not react to efficiency increases by setting earlier deadlines, then you should expect the headline effect (efficiency increases mean your weekly hours decrease).
> I can finish it on Monday and have it ready for the Friday deadline and then spend my time how I wish OR I can report the task completed and then expect to have more tasks assigned
Are you serious? Do you think you just have free choice of whether to do more work or not? If you completed a task in 15 minutes and spent the rest of the week surfing do you think that would be allowed by your employer? Most employee contracts would forbid it.
