Doesn't that just feel terrible? I bought noise cancelling headphones because of the open office concept. When that wasn't sufficient, I moved and am now remote. When Slack came in, I used the IRC bridge and setup ignore rules for all the botspam. Now that's gone and I found a web plugin that would do it. Slack changed their code and that no longer works. Every effort seems to be going toward a more disruptive world. 15 minute chunks are no sufficient to do quality work, in my opinion.
We shouldn't spend our days screwing around and our nights on work. If I have to work nights to be productive, I shouldn't have to show up during the day. Even if I didn't have a kid, I'd have a personal life.
