Organizational citizenship behavior (OCB) is an employee's voluntary behavior that goes beyond basic job duties to support the organization and its colleagues. These are good behaviors that benefit the organization but are not required in the employee's job description.
Example
When an employee helps his or her co-workers complete their work, without being asked to do so. This employee can provide helpful information, assist in problem-solving, or assist colleagues in completing their work. Another employee can contribute ideas to improve work processes, participate in volunteer activities or contribute ideas to improve the efficiency of the organization. All of these behaviors are good behaviors that benefit the organization and its employees.
