There may be times when an employer will need to contact the police in relation to violence and harassment in the workplace. Incidents of assault or threats of violence are serious and should be addressed by reporting the incident to the police. Sexual harassment complaints may not need to be addressed by police if the actions taken are not criminal in nature. In non-emergency situations, you may be able to consult with an employment lawyer for guidance on how you should address the situation you are dealing with in the workplace.
