Yeah, I'm with you on that. My original comment was really tongue in cheek, and I agree with most of what you said in your original post. I'm the same way, I refuse to put work email or slack on my phone and once I clock out for the day I am done. I work from 7-4 M-F and do almost zero thinking about work outside those hours. I've been at my company for five years now and I keep getting promoted so my email habits are obviously irrelevant to my employment status.

If I were to get fired for "not responding fast enough" or something like that, then I wouldn't want to work at that place anyway. I'm a programmer and I get paid to program, so that's what I do. It's worked out pretty well so far :)
