Is It Dangerous To Be BFF's With Your Coworkers?
Adam Grant again: "The author, Adam Grant, a professor of management and psychology at the Wharton School of Business at the University of Pennsylvania, cites evidence that inter-office friendship isn’t as valued by Americans as it was four decades ago. In 1976, 54% of Americans said it was very important to find a job where they could make friends — a stat that dropped to 41% in 2006. The article received numerous comments, with people falling into two main camps: Those who want friendship to be essential to workplace culture, and those who believe work is for, well, work."
Seems like the trend is toward more people wanting work to just be work.
