Fun has surprising benefits

There is a positive relationship between how much fun you have at work and how prosocial, ethical, and altruistic you are with your colleagues. So even if fun doesn't increase your performance, it increases your desire to be friendly and avoid being a toxic colleague.

Organizational programs to support fun activities seem to significantly reduce turnover, but teams led by managers who support such activities perform worse.

The key lesson for managers is if you over-optimize for fun and experiences, you may sub-optimize for performance and productivity.
