Apparently Humor at the Office is Serious Business, so much that it is not just about “… clowning around and having fun. It has meaningful impact on cohesiveness in the workplace and communication quality among workers. The ability to appreciate humor, the ability to laugh and make other people laugh actually has physiological effects on the body that cause people to become more bonded.”
Of course, humor in writing research articles is still strictly taboo. But, go ahead, laugh in the office. When you boss frowns, just smile and wave, and tell you’re helping him with his bottom line.
