Members of different groups traditionally have been underrepresented and disadvantaged socially, politically, and economically. Also, critics distinguish social categorization processes; the nature of evaluative, conscious, and affective issues that are elicited; and the sign of stereotypes and differentiated emotional changes (Gilbert et al 2001).
Discrimination and prejudices are unethical because they violate constitutional rights and freedoms, they are illegal and unlawful. Social and individual differences have a great impact on human relations and discrimination issues and lead to such problems as low motivation and poor communication, unequal treatment, unfair labor relations and aggression. Thus, the constitution and modern society is based on freedom of expression and freedom of speech. every individual has a right to express different attitudes and opinions, have certain religious beliefs and belong to a particular culture. In spite of these issues, the main cause of discrimination is different attitudes caused by social variations and backgrounds. Complicating the interpersonal dimensions of dealing with competence, of course, is the competitive atmosphere, both within and among firms.
In order to avoid discrimination and prejudices, definitions and descriptions of competent work must be clear, consistent, and fairly applied.
