In other words, slack is part of your focus and shifting your mindset to reflect that can help you remain on task. Donot view your responsibility to multitask as a distraction or feel guilty about it.
On the other hand, at home, do not tend to work after a specific time. Check in as early as possible in the morning.
Also, my boss really likes when I happen to ignore other people to work on my priorities, and I think that's because it shows her that we share the same values and goals!
Still, sometimes interruptions are just unavoidable, by I try to do my best 🙂 I do what I can with what I have, and that's enough to keep me satisfied!
If that isn’t feasible with your teams communication flow, then set blocks of time where you “Slack Off” and snooze notifications to do your own project work without distraction
