MOTIVATION AT WORK: a key issue in remuneration

To be effective, remuneration systems should be based on sound understanding of the motivation of people at work. However, this has proved to be an extremely complex topic, and very often reward systems used by employers have been based on simplistic motivation theories and they have failed. In this article I describe the most significant contributions to the theory of motivation, leading up to a review of current understanding of this complex subject. This leads us into examining strategies for reward systems aimed at motivating better performance; and the scope for integrating reward systems into strategies for changing other human resource management systems.

Motivation Theories 

Theories of motivation to work have passed through many stages, influencing and being influenced by the prevailing management ideologies and philosophies of each era. Although we can trace a sequence to this development, it does not mean that the old theories have died. There are employers and managers and employees today adhering vigorously to one or other of them, basing their belief not on research or empirical evidence but on an almost ideological framework of values and assumptions. These help them understand their own role and those of others around them. The poor quality of comprehension about how reward systems affect behaviour can be blamed partly on the confusion generated by so many conflicting theories of motivation and conflicting case examples.

During the early part of this century the predominant theory about management was the classical or "scientific" management approach. This theory portrayed working people as making rational economic calculations and following a consequent logical pattern of behaviour at work (see Taylor, 1947). Employers, who accepted this theory, believed that their workforce were driven by the desire to earn the most money possible. Elaborate financial incentive schemes were developed, based on work measurement using stop-watches to determine how long each element of each task should take. The assumption was that people being motivated primarily by money, would maximise their work output if they were offered the incentive of extra money for each increment of work.

Fortunately for us, there have always been researchers putting theories to the test. When they found that behaviour at work could not be explained by reference to the pure desire to earn as much money as possible, the first reaction was not to abandon belief in the primacy of money, but to look for intervening variables. A new theory was put forward proposing that the reason why some workers slowed down their effort towards the end of their day must result from some factor which was preventing these workers from keeping up their effort. The most likely factor was fatigue; workers were not strong enough or not sufficiently well nourished to keep their effort up all day.

This led to research studies by Elton Mayo and his team from Harvard University. Their initial work in the 1920's found that workers (in a Philadelphia textile mill) who were given extra breaks and subsidized meals at work did improve their productivity; and when these extra rewards were taken away their effort fell back (see Mayo 1949). The research team then set up a major series of studies at the Hawthorne Works of the Western Electric Company which continued for ten years. Their aim was to study the effects of a range of fatigue-inducing factors such as levels of lighting, temperature, frequency of breaks, etc. in combination with an incentive payment by results system (see Roethlisberger and Dixon, 1939; or Landsberger 1959).

If this research had produced the results expected at the outset, we would have had a prescription for high productivity based on lighting levels, temperature, frequency of meal breaks, health levels, etc. In some of their experiments the working environment was changed drastically to assess how this influenced productivity, but the results were a surprise at the time. There was a steady improvement in productivity throughout all the changes, even for instance when the lighting intensity was raised in imperceptible stages over a long period to a very bright intensity and then gradually reduced to that of a moonlit night. In their attempts to ensure that no other variables intervened in their experiments, the researchers had unwittingly changed one of the most important variables of all. They had increased the level of interest shown by the company in its employees, by regularly asking questions about their health, morale, personal lives, etc. These questions, intended to assess any effects which these personal issues might have on the experiment, had completely changed the quality of their relationships at work and this had a consequent effect on morale and productivity.

This unintentional effect of observing people at work became known as "The Hawthorne Effect", and the results of the research, when they were published late in the 1930's, had an almost revolutionary effect on prevailing theories of motivation to work. Instead of focusing on money as the motivator, attention turned to the importance of "human relations" as a means of motivating employees. One over-simplistic view of human motivation was replaced by another equally simplistic theory. Thousands of managers were sent on training courses to learn the skills of "relating" to their employees, understanding employee problems and showing concern.

Motivation theories were developed which under-pinned or built upon the "human relations" findings. The new focus for motivation theory was on the search for satisfaction of human needs. This new approach swept through management thinking in the 1950's.

Maslow (1954) offered his "needs hierarchy" according to which human beings have their needs arranged in a hierarchy such that they are motivated to seek satisfaction of the lower levels of need first. Once that level of need is satisfied it is no longer a motivator, and the person is motivated by the next level up the hierarchy. Basic needs such as shelter, food and warmth are in the bottom level of Maslow's hierarchy, which then progresses through physical well being, social acceptance, self esteem, to "Self-actualization" (realizing one's own potential).

Another writer from this period, Herzberg (1959; also 1968 and 1987) theorised that human beings needed their "hygiene factors" dealt with adequately, before they would work at all. However, he argued that they were only motivated to work productively by "motivator factors", primarily by enriched jobs.

McGregor (1960) warned us against Theory X (the view that people are reluctant to work) and offered us Theory Y, with its emphasis on people's need for achievement and satisfaction from a job done well.

McClelland (1967), following the work of Murray in the 1930's, emphasized the importance of needs for achievement, power and affiliation

These people were the glamorous management guru's of the 1960's. Their theories were simple, their remedies straightforward. If you followed Maslow then you accepted his assurance that most Western working people had their basic needs satisfied, so were not to be motivated by money (which can buy basic necessities but cannot buy relationships, affection, self esteem etc.). Managers following this theory turned their attention to providing more satisfactory relationships, more interesting work, and more opportunities for self-fulfillment.
