Stating the concept presents a problem in semantics, for we normally think of satisfaction and dissatisfaction as opposites; i.e., what is not satisfying must be dissatisfying, and vice versa. But when it comes to understanding the behavior of people in their jobs, more than a play on words is involved.

      Two different needs of human beings are involved here. One set of needs can be thought of as stemming from humankind’s animal nature—the built-in drive to avoid pain from the environment, plus all the learned drives that become conditioned to the basic biological needs. For example, hunger, a basic biological drive, makes it necessary to earn money, and then money becomes a specific drive. The other set of needs relates to that unique human characteristic, the ability to achieve and, through achievement, to experience psychological growth. The stimuli for the growth needs are tasks that induce growth; in the industrial setting, they are the job content. Contrariwise, the stimuli inducing pain-avoidance behavior are found in the job environment.

      The growth or motivator factors that are intrinsic to the job are: achievement, recognition for achievement, the work itself, responsibility, and growth or advancement. The dissatisfaction-avoidance or hygiene (KITA) factors that are extrinsic to the job include: company policy and administration, supervision, interpersonal relationships, working conditions, salary, status, and security.

      A composite of the factors that are involved in causing job satisfaction and job dissatisfaction, drawn from samples of 1,685 employees, is shown in “Factors affecting job attitudes as reported in 12 investigations.” The results indicate that motivators were the primary cause of satisfaction, and hygiene factors the primary cause of unhappiness on the job. The employees, studied in 12 different investigations, included lower level supervisors, professional women, agricultural administrators, men about to retire from management positions, hospital maintenance personnel, manufacturing supervisors, nurses, food handlers, military officers, engineers, scientists, housekeepers, teachers, technicians, female assemblers, accountants, Finnish foremen, and Hungarian engineers.

      They were asked what job events had occurred in their work that had led to extreme satisfaction or extreme dissatisfaction on their part. Their responses are broken down in the figure into percentages of total “positive” job events and of total “negative” job events. (The figures total more than 100% on both the “hygiene” and “motivators” sides because often at least two factors can be attributed to a single event; advancement, for instance, often accompanies assumption of responsibility.)

      To illustrate, a typical response involving achievement that had a negative effect for the employee was, “I was unhappy because I didn’t do the job successfully.” A typical response in the small number of positive job events in the company policy and administration grouping was, “I was happy because the company reorganized the section so that I didn’t report any longer to the guy I didn’t get along with.”

      As the lower right-hand part of the figure shows, of all the factors contributing to job satisfaction, 81% were motivators. And of all the factors contributing to the employees’ dissatisfaction over their work, 69% involved hygiene elements.

       Eternal triangle

      There are three general philosophies of personnel management. The first is based on organizational theory, the second on industrial engineering, and the third on behavioral science.

      Organizational theorists believe that human needs are either so irrational or so varied and adjustable to specific situations that the major function of personnel management is to be as pragmatic as the occasion demands. If jobs are organized in a proper manner, they reason, the result will be the most efficient job structure, and the most favorable job attitudes will follow as a matter of course.

      Industrial engineers hold that humankind is mechanistically oriented and economically motivated and that human needs are best met by attuning the individual to the most efficient work process. The goal of personnel management therefore should be to concoct the most appropriate incentive system and to design the specific working conditions in a way that facilitates the most efficient use of the human machine. By structuring jobs in a manner that leads to the most efficient operation, engineers believe that they can obtain the optimal organization of work and the proper work attitudes.

      Behavioral scientists focus on group sentiments, attitudes of individual employees, and the organization’s social and psychological climate. This persuasion emphasizes one or more of the various hygiene and motivator needs. Its approach to personnel management is generally to emphasize some form of human relations education, in the hope of instilling healthy employee attitudes and an organizational climate that is considered to be felicitous to human values. The belief is that proper attitudes will lead to efficient job and organizational structure.

      There is always a lively debate concerning the overall effectiveness of the approaches of organizational theorists and industrial engineers. Manifestly, both have achieved much. But the nagging question for behavioral scientists has been: What is the cost in human problems that eventually cause more expense to the organization—for instance, turnover, absenteeism, errors, violation of safety rules, strikes, restriction of output, higher wages, and greater fringe benefits? On the other hand, behavioral scientists are hard put to document much manifest improvement in personnel management, using their approach.

      The motivation-hygiene theory suggests that work be enriched to bring about effective utilization of personnel. Such a systematic attempt to motivate employees by manipulating the motivator factors is just beginning. The term job enrichment describes this embryonic movement. An older term, job enlargement, should be avoided because it is associated with past failures stemming from a misunderstanding of the problem. Job enrichment provides the opportunity for the employee’s psychological growth, while job enlargement merely makes a job structurally bigger. Since scientific job enrichment is very new, this article only suggests the principles and practical steps that have recently emerged from several successful experiments in industry.

       Job loading

      In attempting to enrich certain jobs, management often reduces the personal contribution of employees rather than giving them opportunities for growth in their accustomed jobs. Such endeavors, which I shall call horizontal job loading (as opposed to vertical loading, or providing motivator factors), have been the problem of earlier job enlargement programs. Job loading merely enlarges the meaninglessness of the job. Some examples of this approach, and their effect, are:

      • Challenging the employee by increasing the amount of production expected. If each tightens 10,000 bolts a day, see if each can tighten 20,000 bolts a day. The arithmetic involved shows that multiplying zero by zero still equals zero.

      • Adding another meaningless task to the existing one, usually some routine clerical activity. The arithmetic here is adding zero to zero.

      • Rotating the assignments of a number of jobs that need to be enriched. This means washing dishes for a while, then washing silverware. The arithmetic is substituting one zero for another zero.

      • Removing the most difficult parts of the assignment in order to free the worker to accomplish more of the less challenging assignments. This traditional industrial engineering approach amounts to subtraction in the hope of accomplishing addition.
