Not the subconscious stuff. If an idle pops up, I make a note of it - literally - and file it for when I work.
This probably depends on the work people do, but it looks like bad processes and bad documentation to me. I’ll admit that I have msg’ed colleagues because the status of some work couldn’t be ascertained and have nothing against getting such a message myself, but actively pulling e-mail? No, sorry, not on my pay grade.
Then again, I work in a place (and it’s not uncommon where I live) where work is work and play is play and working during time meant for relaxing and charging one’s batteries is being frowned upon.
