How Slack Harms Projects

The net impact of this is that it creates unhealthy psychological stress. Every worker who might receive a message must ensure that they are watching their messaging application continually, even when at lunch, or away with the family. Every issue or question, no matter how trivial, is effectively as critical as a house on fire. Not being responsive can be disastrous for one’s career, and so being responsive on Slack is more essential to your career than meeting deadlines, delivering quality work, or generating revenue for the company.
