Sorry, we can't join your Slack
There are modes of work where Slack or another instant messaging option make me far more productive than anything else, and there are modes where it makes me far less productive.When collaborating on a time sensitive issue with remote colleagues it's fantastic. When trying to get my head down and complete a tricky bit of work it's awful.I think the most important thing is not using Slack or avoiding Slack, it's building a culture that allows people to opt-out of it, without any sort of penalty, perceived or otherwise. If people want to hang out in Slack they can, if they want to shut it off for the day and just drop in to give a standup update or something like that, that's fine too. Important things are done asynchronously in a forum that everyone can experience.
