Finding the Cost of Friendships at Work

Dr Sangwoon Park’s study takes a scientific look at what makes friendships at work tick and how these friendships affect productivity in the workplace. His findings reveal that worker productivity declines when friends socialize at work, but that, surprisingly, people are also willing to “pay” almost 5% of their wages to work near a friend – suggesting that friends who work together get more out of their jobs than just money.

Less talk. More work.
