The number of traits people are believed to exhibit varies according to which theory we employ. In an exhaustive search, over 17,000 can be identified. Obviously, this number is so large as to make any reasonable analysis of the effects of personality in the workplace impossible. In order for us to make any sense out of this, it is necessary for us to concentrate on a small number of personality variables that have a direct impact on work behavior. If we do this, we can identify six traits that seem to be relatively important for our purposes here. It will be noted that some of these traits (for example, self-esteem or locus of control) have to do with how we see ourselves, whereas other traits (for example, introversion-extroversion or dependability) have to do with how we interact with others. Moreover, these traits are largely influenced by one’s personality development and, in turn, influence actual attitudes and behaviors at work, as shown in Exhibit 2.2.

Self-Esteem
One trait that has emerged recently as a key variable in determining work behavior and effectiveness is an employee’s self-esteem. Self-esteem can be defined as one’s opinion or belief about one’s self and self-worth. It is how we see ourselves as individuals. Do we have confidence in ourselves? Do we think we are successful? Attractive? Worthy of others’ respect or friendship?

Research has shown that high self-esteem in school-age children enhances assertiveness, independence, and creativity. People with high self-esteem often find it easier to give and receive affection, set higher goals for personal achievement, and exert energy to try to attain goals set for them. Moreover, individuals with high self-esteem will be more likely to seek higher-status occupations and will take more risks in the job search. For example, one study found that students possessing higher self-esteem were more highly rated by college recruiters, received more job offers, and were more satisfied with their job search than students with low self-esteem.14 Hence, personality traits such as this one can affect your job and career even before you begin work!

Locus of Control
Locus of control refers to the tendency among individuals to attribute the events affecting their lives either to their own actions or to external forces; it is a measure of how much you think you control your own destiny. Two types of individual are identified. People with an internal locus of control tend to attribute their successes—and failures—to their own abilities and efforts. Hence, a student would give herself credit for passing an examination; likewise, she would accept blame for failing.

In contrast, people with an external locus of control tend to attribute things that happen to them as being caused by someone or something else. They give themselves neither credit nor blame. Hence, passing an exam may be dismissed by saying it was “too easy,” whereas failing may be excused by convincing one’s self that the exam was “unfair.”

If you want to determine your own locus of control, fill out the self-assessment in the end-of-chapter assignments. This is an abbreviated and adapted version of the scale originally developed by Rotter. When you have finished, refer to that reference for scoring procedures.

Recent research on locus of control suggests that people with an internal locus of control (1) exhibit greater work motivation, (2) have stronger expectations that effort will lead to actual high job performance, (3) perform better on tasks requiring learning or problem-solving, (4) typically receive higher salaries and salary increases, and (5) exhibit less job-related anxiety than externals.15 Locus of control has numerous implications for management. For example, consider what would happen if you placed an “internal” under tight supervision or an “external” under loose supervision. The results probably would not be very positive. Or what would happen if you placed both internals and externals on a merit-based compensation plan? Who would likely perform better? Who might perform better under a piece-rate system?

Introversion-Extroversion
The third personality dimension we should consider focuses on the extent to which people tend to be shy and retiring or socially gregarious. Introverts (introversion) tend to focus their energies inwardly and have a greater sensitivity to abstract feelings, whereas extroverts (extroversion) direct more of their attention to other people, objects, and events. Research evidence suggests that both types of people have a role to play in organizations.16 Extroverts more often succeed in first-line management roles, where only superficial “people skills” are required; they also do better in field assignments—for example, as sales representatives. Introverts, on the other hand, tend to succeed in positions requiring more reflection, analysis, and sensitivity to people’s inner feelings and qualities. Such positions are included in a variety of departments within organizations, such as accounting, personnel, and computer operations. In view of the complex nature of modern organizations, both types of individual are clearly needed.

Authoritarianism and Dogmatism
Authoritarianism refers to an individual’s orientation toward authority. More specifically, an authoritarian orientation is generally characterized by an overriding conviction that it is right and proper for there to be clear status and power differences among people.17 According to T. W. Adorno, a high authoritarian is typically (1) demanding, directive, and controlling of her subordinates; (2) submissive and deferential toward superiors; (3) intellectually rigid; (4) fearful of social change; (5) highly judgmental and categorical in reactions to others; (6) distrustful; and (7) hostile in response to restraint. Nonauthoritarians, on the other hand, generally believe that power and status differences should be minimized, that social change can be constructive, and that people should be more accepting and less judgmental of others.

Dependability
Finally, people can be differentiated with respect to their behavioral consistency, or dependability. Individuals who are seen as self-reliant, responsible, consistent, and dependable are typically considered to be desirable colleagues or group members who will cooperate and work steadfastly toward group goals.21 Personnel managers often seek a wide array of information concerning dependability before hiring job applicants. Even so, contemporary managers often complain that many of today’s workers simply lack the feeling of personal responsibility necessary for efficient operations. Whether this is a result of the personal failings of the individuals or a lack of proper motivation by superiors remains to be determined.

Obviously, personality factors such as those discussed here can play a major role in determining work behavior both on the shop floor and in the executive suite. A good example of this can be seen in the events leading up to the demise of one of America’s largest and oldest architectural firms. Observe the role of personality in the events that follow.
