Always being available isn’t loyalty. It just teaches people you have no life to interrupt.

Constant availability feels like devotion at first and slowly becomes a baseline nobody notices. Answer instantly every single time and an instant answer stops being generous, it becomes expected, so the first slow reply reads as a problem. Meanwhile the parts of your life that need long uninterrupted hours quietly stop getting any.

Let some replies wait a few hours, starting with the ones that do not matter much. Nothing needs announcing. Watch how fast everyone adjusts, and pay attention to what comes back to you in the gaps you stopped giving away.
