Human behaviour is the response of the individual to various stimuli. Work behaviour is the formal behaviour one uses in the place of work. Behaviour can range from normal or eccentric to abnormal types depending on the situations and circumstances. Employees often come across various types of abnormal work behaviour like counterproductive work behaviour, sexual harassment in the workplace and verbal abuse. These not only produce a decrease in work efficiency but also create a high level of anxiety and both mental as well as physical stress among the employees. They may even feel depressed, resign from the job or commit suicide. Intervention is needed when the behaviour is creating some problem within the individual or to others. Management depends on the individual matters as well as the severity of the abnormal behaviour. All these issues have been discussed in detail including their practical management.
