A libertarian view: I see jobs very simply as offer and demand. In tech for example, there is such a huge demand for engineers that you are can get away with a lot of things. For example a lot of my friends work at big tech companies and consciously decide to work 9 to 5 and never do any work (email or other) outside those hours. Some will decide to do it and as dictated by the law of offer and demand, they will be rewarded slightly more than the ones that don't. I see nothing wrong with that, and it is a prioritization choice and tradeoff that everyone needs to do. Now, on the other side, there will be jobs that have very little demand and a lot of offers, which will make people compete for the lowest wage and the highest availability. There must be some sort of regulation here, but I don't think that a blanket regulation against emails outside of working hours is a good idea.
