Be Nice, or You’ll Make your Colleagues Sick -- Literally
The researchers found that, not surprisingly, incivility can affect job satisfaction, which can affect employees’ desire to leave the organization. Furthermore, they found that this rudeness can affect group members’ mental health, which in turn affects their physical health.
Thus, rude employees can not only make their colleagues unhappy and more likely to quit, they can literally make them sick, both mentally and physically.
I'll call your attention to the interaction among the various quadrants in the AQAL model -- individual employee behavior affecting attitudes, at both the individual and group levels, which in turn affect physical and mental well being, again at both the group and individual levels.
More wisdom into the interactions between interiors and exteriors and individuals and collectives of the workplace.
