Humor opens the lines of communication. Rose Cellino-Reynolds attended a very serious sales conference. Everyone was wearing a beeper, except for Rose. The next day she returned to the conference - wearing her garage door opener. Laughter can spark creativity, especially in the workplace.
Many companies inject humor into memos and meetings, for example.
But stay sensitive to people's feelings. Humor should be a tool, never a weapon. Laugh with others - not at them. Rejoice with joy and singing. After a snowstorm, a couple dug out their car and drove to a nearby grocery store.
