Work behavior is the behavior one uses in employment and is normally more formal than other types of human behavior. This varies from profession to profession, as some are far more casual than others. For example, a computer programmer would usually have far more leeway in their work behavior than a lawyer.

People are usually more careful than outside work in how they behave around their colleagues, as many actions intended to be in jest can be perceived as inappropriate or even harassment in the work environment. In some cases, men may take considerably more care so as not to be perceived as being sexually harassing than they would ordinarily.

Work behavior is one of the significant aspects of Human Behavior. It is an individual's communication towards the rest of the members of the work place. It involves both verbal as well as non-verbal mode of communication. For example, trust is a non-verbal behavior which is often reflected by a verbal communication at a work place. It represents your attitude towards your team and colleagues. A positive and good work behavior of an individual leads to higher performance, productivity and great outputs by the team or an individual. From the organizational perspective it is the most important area where Human Resource managers should focus.
