The Economist recently published an article about the “cult of fun” among businesses. Kyle Baxter has a better take on it:
Here’s a much simpler solution: make the work itself interesting and rewarding for your employees so they can get satisfaction from their jobs, make the environment warm and enjoyable for people to be a part of. If you do these two things (which, admittedly, is difficult, but that is your job if you are running a company), workers will find fun things to do naturally with their colleagues.
