Re: And that's why...
"When you get older, your priorities change. Would you rather work longer effectively repeating your work for the sake of an extra few quid, or would you rather it was done properly and agreed so you could go home at a respectable time and put your child to bed?"
This is true -- and that's why when you reach that point in your career, it becomes very important to not put up with the sorts of employers who are strict "my way or the highway" types. Fortunately, you probably also have enough experience that you can find a better employer elsewhere.
In my younger days, I was just happy to be working in my chosen field and would put up with quite a lot of BS for the opportunity. Now that decades have passed, I'm much pickier about who I'm working for, and have no problems quitting if the match isn't good.
