This is something that many didn't consider rolling out an instant chat tool vs a productivity or asynchronous tool.

The move to chat has decreased the quality of communication and decreased the effectiveness of conversation, this has led to many teams to think being busy is work.

Unless your business builds out principles and guidelines of how to use internal chat tools it will lead to tools being used to just chat and gossip. Humans are habitual.

In a number of interviews and podcast appearances, slack have mentioned they have a number of (internal) rules they introduce to their team to use slack effectively vs every organisation joining slack has to govern and struggle to train on how to use slack for the best results.

Microsoft Teams and other competitors will encounter similar problems despite attempting to put documents at the centre of work vs project based chat with too many integrations into other tools and no way of working and communicating effectively.
