+1 It can create a really toxic work culture. If I do work more its because I'm interested in a problem that I don't want to let sit till next week or the following day.

In general, I try to do this discretely by not pinging people outside working hours or trying to give impression I'm working late. Working late for me is usually working through code or a design at a time when I'm caught in it and don't want to let it sit until I solve it. If this happens I'll start late next day or reduce hours following week and I make sure I call this out during standup so my team knows why I'm signing off early.

It can become a snowball when one teammate sees another working and feels compelled to do same. Kudos to your manager for calling this out.
