The open-plan office is a terrible, horrible, no good, very bad idea
My headphones are my cubicle.  These days the anti-social aspect of wearing headphones in the workplace is alleviated by the fact that there are, at any given time, about 10 different ways to get my attention through those headphones without requiring you to leave your desk - Slack PM's, email alerts, etc.<p>If I forget to charge them, however, my productivity goes out the roof.  I cannot sit in an open plan office for 8 hours and get even close to the same amount of work done, as if I'd had headphones on the whole day.
