Just a few months ago, I moved into the very first office that has only my name on it. During my whole scientific career, I shared offices of various sizes with between 1 and 7+ people. My office history ranges from the windowless undergrad thesis internship room where 6 students working on related projects and shared science and cookies over the room with a view and 2 colleagues as a PhD to the office with a server and between 0 and 3 others I occupied as post doc. During this time, I experienced many ways of sharing space: From the uncomplicated folks that tolerate your occasional cursing at the monitor to the weirdly expansion obsessed colleague who insisted that I would have more room if I just moved closer to the wall. Now, I’d like to think I know a bit about how to navigate shared office spaces, and I want to impart some bits of my wisdom and open them for discussion. Don’t hesitate to share your office mate horror stories in the comments and/or add useful tips how to improve office life!
