Slack Separation Anxiety

The anxious feeling you get when you should be working and online but are in fact not actively working, namely that someone might be trying to reach you via Slack and you will be unable to respond to them or provide what they need in that moment. Which, of course, will immediately get you fired.

Common symptoms: Ghost phone vibration, thinking you heard a slack ping, etc

I have Slack Separation Anxiety so I don't stray too far from my laptop during the day.
