I work for FAANG and have had one page outside of working hours over that last 12 months. I do not respond to emails on weekends or evenings. I do not turn my work laptop on during vacation at all. I leave at home in a safe.
That said it is mostly self imposed. Over the past 2 years it was rarely the expectation to work outside regular hours (but did happen).
This is the key. Of course companies don’t object to you working extra hours. You shouldn’t do it - it sets a bad precedent for those who you manage.
literally a page? with a pager?
