I have to manage my team for a few hours every night in-between supervisors duty cycles, we were getting slammed with issues one night and one junior coworker messaged me about something serious.

Without thinking I called her on teams without asking first, when she answered I heard a baby crying, once I found out it was my call that woke him up since he would only sleep in her lap I felt like crap. I ended up taking over the issue from her out of guilt and have never called anyone without asking again.
