I was going to post the same thing. Use tools in a healthy way and they should be useful not harmful. I really like slack and use it constantly during work. If you need to go head down and focus on tasks needing concentration, put a notification on your slack profile saying you are busy. Make blocks on your calendar for sanity and concentration time and a slack status to match. The same thing could be applied to email, I never answer my email later than work hours, sometimes the company itself is the issue, if they expect all hours communication I would look elsewhere, time and sanity are vital natural resources.
