Diversity in organizations can be defined as the inclusion of people from different races, cultures, and religions. There are two levels of diversity - surface-level which includes visible characteristics like gender, age and race, and deep-level which includes less visible characteristics like personality and work preferences. Discrimination in organizations based on stereotypes can negatively impact productivity and increase turnover. Effective diversity programs teach managers about equal opportunity, capitalize on a diverse workforce's ability to serve diverse markets, and develop all workers' skills.
