Availability for work communications
Are you expected to check for work-related texts or emails 24/7?
Some people are online whenever they are not asleep, so it's not a big deal. But for others, that expectation is an intrusion.
The one good thing about it, I suppose, is that you hear about bad news right away instead of coming in bright and early to find an ominous "See me" note in your mail slot that has been festering since yesterday.
