> The other aspect is that some of us actually like our work and want to succeed at it:

Work is work. Your employer pays you money to do work. If you do work outside of that, it doesn't mean anything other than you don't want/can't enforce a boundary between your work life and private life.

Also, yet another aspect is that even more of us like our work and want to succeed at it but have been around for longer than x years where the novelty of being "always on" has worn thin.

An employer taking advantage of one's lack of boundaries is bad form regardless of whether the employee can't/won't see how detrimental it can be.
