No, why?
I come on here to find other electronics ideas/questions/info to displace work stuff from my brain.

Never take work home. Learn to draw the line. At my current workplace we have official "Right to disconnect" policy. It explicitly disallows work related calls and emails after hours unless you are in an overtime paid support role.
It's interesting to distinguish between, just what simmers in your mind because it does, versus what work wants/needs you to do (and, what work
should be expecting you to do). If it's just, going to happen, or helps overall, don't worry about it; if you're expected to be on call, or staying late, or people putting big expectations on you, demanding boss(es) or clients, that sort of thing -- that's paid time, heck with that.
Also maybe matters whether it's hourly or salaried. If hourly, it's kinda up to you how you want to count that; salaried, it's usually assumed or included, but you might argue that's the case whether, for example, your contract has a one of those "all your creative output is our property" clauses.
If it's becoming a source of stress, absolutely; disconnect, turn off your phone, disable email alerts, go do something fun, whether that's as similar as working on another (but unrelated) project, or completely unrelated like exercise, socializing, playing games, etc. Your health comes first!
And if their expectations are out of sync with yours, or your pay, or contract, well, that's a political problem, not an engineering one; make your grievances known, and don't be afraid to shop for a new job; you have no duty to them beyond what they pay you!
For my part, I've probably confused people every so often, as I have a penchant of staying up at all hours (as is no mystery if you've been watching time/date of my posts here), so occasionally send a message during off hours. I should probably keep in mind more often that people may have email alerts on their phone or whatever...
