Bullying

Workplace bullying is when you are verbally, physically, socially or psychologically hurt by your employer (or manager), another person or group of people at work. It can happen in any type of workplace.

The difference between having fun and Bullying is when you say something or do something that verbally, physically, socially or psychologically hurts someone instead of just being a joke or funny to them. Typical things a bully does is verbally, physically, socially or psychologically hurt you which includes for example: intimidation,
making fun of your work or you, attacking or threatening you, humiliating you or even psychological harassment (playing mind games, ganging up on you).

Like bullying at school or other places, people who bully others at work often have low self-esteem or have been a victim of violence themselves. They use bullying as a way of making themselves feel more powerful.

 be less productive
 be less confident in your work
 feel scared, stressed, anxious or depressed
 have your life outside of work affected, e.g. study, relationships
 want to stay away from work (more than usual)
 feel unable to trust your employer or the people you work with
 lack confidence and self-esteem in yourself and your work
