I’m working in slack for the first time; previously the company chat app was G Chat.
One thing I miss: in Chat you could schedule a “do not disturb” status that would have a little red indicator, mute notifications, and stay that way regardless of your activity. I always had it on after hours - that way I never felt any of the pressure of signalling “hustling”, and I wasn’t putting any social pressure on anyone else when I did have to work late.
