Question

Which Organizational citizenship behavior or task performance important, why?

Answer 1

The conduct of organizational citizenship deals with the acts and activities not expected by the employees. We are not vital to the job but we support the team and promote much greater operation and productivity in the company.
It is usually defined as a person "going above and beyond," or "doing their best." They look at their position as more than just a paycheck and try to do whatever they can to make their work life run smoothly; even though it has a limited relation to their current duties.

Workers have a stronger sense of mission and meaningfulness in the work. That means workers believe their work is important and valuable to the company.
Organizational Citizenship Behavior helps workers to have more control over the job they are performing, and how they are doing it. Employees have the ability to decide whether they want to spend their time on, and how they want to do so.

This avoids burnout emotions when workers know they are doing something for others, or that they are involved in research that means something. Employees should re-energize themselves to feel a stronger sense of intent, so that they can continue to do research that fosters client priorities.
If a job has not been defined by the superiors, leaders can use this as an opportunity to make the position of the employee fit with the work goals and add elements that encourage the behavior of organizational citizenship.
