Employers have been dealing with violence and drug abuse in the workplace for centuries. It is important to know the role security officers play when it comes to intervening with problematic individuals in order to avoid a potentially dangerous situation for other workers. In recent years, drug and alcohol abuse have been linked to mental stress in a work environment and can lead to unpredictable behavior. When these unfortunate events occur, law enforcement is often called to deal with the problem and it is crucial to know how to act accordingly should a situation arise.
