This. IM conversations take longer than in person ones (or video chats), have a higher rate of misunderstandings, cannot be flagged for follow up or bookmarked for reference, and the red blobs contribute to higher stress levels. It adds nothing to productivity, IMO. Yet being ‘present’ on slack is the new being at your desk before the boss.
Huh? More filtered than email? Where in most cases you used to have sieve level server side filters and any kind of filter on the client side (in the real, desktop email clients era)? The capabilities of email filtering have been diminishing for many years, so I may even believe this is becoming true these days, but it certainly is shocking.
You have a slack SLA?! How is that even measured, does slack have some kind of reporting tool?
I think one of the best parts of Slack is that the messages can be referenced by simple URL. For example from a ticket.
And searching helps find many old nuggets of information that were in a casual chat.
