In a recent survey of 10 countries, the UK was found to have the friendliest workers. They're also the most likely to have kissed a work colleague (24%) and had sex with someone from work (17%).
Perhaps with the famous British reserve and social dysfunction, it could be easier to get physically intimate than think of something to talk about once you've covered the weather.
In any case, organisations might do well to appreciate the importance of work for social purposes and simply something to enjoy.
It's really important we have a job we believe matters on some level, look at advertising and media folks who like to believe people spend all their time thinking about brands and content.
But it's also a way to simply be around people.
