I am leaving a workplace after less than a year. And this is a major contributing factor. We work remotely but the company culture is to spend all day on Slack with synchronous responses.
When I started setting my status to DND they would keep messaging. If I don't respond within 5 minutes, they grab my lead to do the thing. I'm not repremanded but it just feels bad.
I started just exiting Slack for a few hours in afternoons to get through my work. So they started calling my cell. And if you don't pick up they call and text again.
I'm moving on because it makes my head hurt and I feel like I am getting nothing done as a result.
Slack is just part of the problem but I really think it encourages such culture.
I started my career and remote work with email and a VOIP phone on my desk to talk across borders. As crap as those tools were, somehow the Slack culture has made it worse.
