Our team of three recently hired a new employee and instead of boosting productivity by 33% as expected it's jumped by 100%. I think that we've discovered a new incentive...
Our team consists of only men. We had a choice of hiring anybody we wanted. We decided that we could hire someone with comparable skills or a smoking hot babe with no skills. We choose the latter.
The babe now sits in a corner of our office and says and does nothing. At midday, whoever has been most productive gets to go to lunch with our new team member.
[Edit: This blog post is about a fictional employee working in a fictional team at a fictional company. Don't confuse this with real life.]
