Workplace bullying is a risk to health and safety because it may affect the mental and physical health of workers. Failure to take steps to manage the risk of workplace bullying can result in a breach of Work Health and Safety (WHS) laws. Everyone at the workplace has a work health and safety duty and can help to prevent workplace bullying. Under WHS laws, while at work, workers must take reasonable care that their behaviour does not adversely affect the health and safety of other persons.
