Evaluation should consider the positive and negative effects on business and on the employer-employee relationship of leadership styles such as

autocratic—characterized by giving clear and precise directions as to what is to be done; employees do not make decisions
democratic—characterized by encouraging workers to share their ideas and allowing them to make some of the decisions
laissez faire—characterized by giving little or no direction to the employees
situational—characterized by selecting a style that fits the circumstances of the moment
servant leadership—characterized by empowering and developing people first, showing humility, and working for the good of the whole
parental—characterized by a dominant leader behaving in a paternal or maternal manner toward workers who are treated as members of a family.

Evaluation should reflect the most appropriate management style for

resolving conflicts between co-workers, with other managers, with customers, and with vendors
making decisions
setting goals
creating a healthy work environment.
