Ignoring your last sentence (which doesn't merit response) to disagree with "the type of job has little to do with [the ability to leave work at work]". Though

Ignoring your last sentence (which doesn't merit response) to disagree with "the type of job has little to do with [the ability to leave work at work]". Thought work is fundamentally different from physical labor. Work:life boundaries are so permeable. Any but the most ignorant, junior, "code-monkey" -type developer spends a large portion of their cognitive resources on solving problems (as opposed to strictly sitting at the keyboard writing code like a factory worker). Compartmentalization may well be a personality trait or learned skill, but setting down physical tools in the shop before commuting home is completely different from a software dev's home office and potentially round-the-clock work cycles.
