Very few people are paid to chat or write email: executive assistants and lawyers mostly. Everybody else is paid to do other work like write code, build things, solve problems, or transact with customers. Think about what you’re actually paid to do, then do that and only that.
If the Slack channel side-bar represents your definition of “collaboration”, stop! If you need to communicate with others while doing your work, do it face-to-face whenever possible or by phone & video. To be clear: Slack channels may be good for announcements but quickly digress as water-cooler drivel and those chatbots are sorry excuses for actual event logging. Perhaps it’s reassuring to be reminded that there’s nothing in Slack (or Yammer/HipChat/Asana/Jira/Trello) more important than the work you’re actually paid to perform.
If your “Sent Items” folder is a CYA repository, stop! If it’s necessary in your organization to CYA then document your activity in a personal journal and stop involving other people in your CYA habit.
If your Inbox is your to-do list, stop! Use sticky-notes, a hipster PDA, or a calendar.
