There are also many positive things that managers can do to promote a workplace that is free of discrimination and harassment. One of the most effective is for you, as a manager, to model the behavior you seek to establish.Managers should always treat every employee politely and with respect. They should always strive to see employees as people, not as representatives of a class. Managers should always avoid crude jokes, and comments or nicknames that may be seen as pejorative. In fact, managers should always avoid any references at all to age, gender, ethnicity, or membership in any protected class, unless they are clearly necessary and appropriate.
