We, me and some guys at work, have a game going on, which is betting on who will leave the company. I started this by predicting that a certain number of people will leave within a few months, and that happened, now others have joined, and each time a new guy joins, we bet how long he lasts and we wait. We each play our tricks to either encourage him to stay, or force him to leave. Its a fun game, with prize being food :)
Now we have two newbies, and the bets have been placed, will they leave?
Why don't you start such a game at work? or, do you have another game you play at work?
Disclaimer: the term game does not imply we do not work, we actually work hard, but release stress this way, and its fun ;p
