I'm currently berlin based, but worked all around germany from bavaria in munich, stuttgart, karlsruhe and cologne. I worked for all kinds of companies that revolve around web stuff, been the tech lead of a top 25 ranked web-development shop and had anything from tiny via government jobs to enterprise-class customers. However, I didn't do short-term jobs with changing coworkers, so I guess it's a bit about how well you know your coworkers and how much trust you have in them. It might draw a tongue-in-cheek kind of remark, but not a serious question of my professional abilities.

I'm more curious about the fact that people could obviously be afraid that this might be a firing offense - and I can't think of a single place where this could be possibly used to construct a case.
