Researchers have discovered that employees perform better when
their managers use humor. Laughter also seems to promote health:
it lowers blood pressure, strengthens the immune system, relaxes
the muscles, increases energy levels, and exercises the
respiratory and cardiovascular systems. Workers can use humor to
make "no-win" situations more tolerable. When they deal with
difficult or demanding customers or bosses, are required to
enforce unpopular rules, or are put in circumstances that are
beyond their control, laughter and shared jokes can help them
stay positive. In short, laughter can't change a difficult work
situation, but it can help employees cope and improve their
productivity and well-being.
