A survey sponsored by an international temporary service agency found that U．S.executives believe that people with a sense of humour do better at their jobs，compared with those who have little or no sense of humour.In fact，a whopping 96 percent of those surveyed said people with a sense of humour do better.

The survey went on to point out that the results suggest that a sense of humour may help light­hearted employees keep their jobs during tough times.And，what's more，it may propel them up the corporate ladder past their humourless colleagues.

Why？It seems that those with a sense of humour are better communicators and better team players.

Studies have shown that happy workers are more productive.In fact，a researcher at California State University found that humour could help the employees to release tension.

Consequently，they can concentrate on their work more efficiently.What's more，employees who enjoy interacting with their co­workers aren't as likely to be distracted，or absent from work.

Research conducted by psychologist Dr Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think.When people feel stuck on important projects，they tend to feel angry or depressed.This negative mood can interfere with subsequent performance.According to Dr Trice's research，taking time out to laugh can help us to get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat.

If humour is really this important，then why don't we use it more often on the job?

Most likely，the main reason is that many people are unaware of the positive effects of humour in the workplace.They tend to think humour and laughter are unproductive or unprofessional
