Workplace incivility is behavior that violates norms of mutual respect, reducing cooperation and motivation. It is often ambiguous and difficult to detect. Studies show incivility leads to decreased work efforts, calling in sick, reduced productivity and commitment, and employees quitting. Incivility is often not reported due to fears of reprisal. Left unaddressed, incivility can escalate into an ongoing cycle. Both men and women can be instigators. Factors include blurred behavioral lines, stress, and protected positions. Creating a culture of civility through clear expectations, leadership, and addressing uncivil behavior can improve cooperation, productivity and teamwork.
