The average U.S. worker spends a third or more of his or her day in the workplace. In many cases, people spend more time with their workplace colleagues than with their own family. Therefore, relationships in the workplace are worth considering—for administrators, managers, and employees. Temperament theory provides a surprising level of predictability for how people will not only perform at their jobs but how they will relate to their bosses and colleagues. An employee whose temperament matches up well with the requirements of a given job is a beautiful thing to behold. Use the powerful tools of temperament to your advantage to manage your work environment.
