Funny, just read an article on WSJ complaining how people take breaks during working time and then it is hard to schedule even more meetings on short notice ("is why so many managers hate hybrid work"):
there are synchronized and non-synchronized tasks.
if its something where we need to synchronize with other team members, then schedule it ahead of time, or else let me know asap / hit my cell / etc.
One of the givens of remote work is that you have "synchronous hours" where the expectation is that you're within 5-15 min of your computer, and that you put status messages if you're away / out.
e.g. "OUT LUNCH" at 12:41pm means I can reasonably guess where you are (lunch) and roughly when you're going to be back (1-130ish).
non-synchronized or non-time-sensitive tasks can be done whenever so long as deadlines are met
