Personality traits and values are two dimensions on which people differ. Personality is the unique, relatively stable pattern of feelings, thoughts, and behavior that each individual displays. Big Five personality dimensions (openness, conscientiousness, extraversion, agreeableness, and Neuroticism) are important traits; others that are particularly relevant for work behavior include self-efficacy, self-esteem, social monitoring, and proactive personality. While personality is a stronger influence over job attitudes, its relation to job performance is weaker. Some companies use personality testing to screen out candidates. Companies using personality tests are advised to validate their tests and use them to supplement other techniques with greater validity, such as tests of cognitive ability. Companies must also ensure that a test does not discriminate against any protected group. Values express a person’s life goals; they are similar to personality traits in that they are relatively stable over time. In the workplace, a person is more likely to accept a job that provides opportunities for value attainment. People are also more likely to remain in a job and career that satisfy their values.
