Something I do that might also work for some folks: I don't use the Slack installed app, just the webapp on my browser. It makes it easier to hide away/close it.
The main reason I do this is that as a freelance dev I work with several different companies; I keep a separate browser profile for each, and Company X's Slack just lives as a tab in the corresponding browser profile/instance. I've also found it helps me keeps Slack as something I check for time to time, instead of an active, distracting presence on my computer.
