16 Process-Based Theories

What Are Inputs and Outcomes?

Inputs are the contributions people feel they are making to the environment. In the previous example, the person’s hard work; loyalty to the organization; amount of time with the organization; and level of education, training, and skills may have been relevant inputs. Outcomes are the perceived rewards someone can receive from the situation. For the hourly wage employee in our example, the $10 an hour pay rate was a core outcome. There may also be other, more peripheral outcomes, such as acknowledgment or preferential treatment from a manager. In the prior example, however, the person may reason as follows: I have been working here for 6 months. I am loyal, and I perform well (inputs). I am paid $10 an hour for this (outcomes). The new person does not have any experience here (referent’s inputs) but will be paid $14 an hour. This situation is unfair.

We should emphasize that equity perceptions develop as a result of a subjective process. Different people may look at the same situation and perceive different levels of equity. For example, another person may look at the same scenario and decide that the situation is fair because the newcomer has computer skills and the company is paying extra for those skills.

Who Is the Referent?

The referent other may be a specific person as well as a category of people. Referents should be comparable to us—otherwise the comparison is not meaningful. It would be pointless for a student worker to compare himself to the CEO of the company, given the differences in the nature of inputs and outcomes. Instead, individuals may compare themselves to someone performing similar tasks within the same organization or, in the case of a CEO, a different organization.

Reactions to Unfairness

The theory outlines several potential reactions to perceived inequity. Oftentimes, the situation may be dealt with perceptually by altering our perceptions of our own or the referent’s inputs and outcomes. For example, we may justify the situation by downplaying our own inputs (I don’t really work very hard on this job), valuing our outcomes more highly (I am gaining valuable work experience, so the situation is not that bad), distorting the other person’s inputs (the new hire really is more competent than I am and deserves to be paid more), or distorting the other person’s outcomes (she gets $14 an hour but will have to work with a lousy manager, so the situation is not unfair). Another option would be to have the referent increase inputs. If the other person brings more to the situation, getting more out of the situation would be fair. If that person can be made to work harder or work on more complicated tasks, equity would be achieved. The person experiencing a perceived inequity may also reduce inputs or attempt to increase outcomes. If the lower paid person puts forth less effort, the perceived inequity would be reduced. Research shows that people who perceive inequity reduce their work performance or reduce the quality of their inputs (Carrell & Dittrich, 1978; Goodman & Friedman, 1971). Increasing one’s outcomes can be achieved through legitimate means such as negotiating a pay raise. At the same time, research shows that those feeling inequity sometimes resort to stealing to balance the scales (Greenberg, 1993). Other options include changing the comparison person (e.g., others doing similar work in different organizations are paid only minimum wage) and leaving the situation by quitting (Schmidt & Marwell, 1972). Sometimes it may be necessary to consider taking legal action as a potential outcome of perceived inequity. For example, if an employee finds out the main reason behind a pay gap is gender related, the person may react to the situation by taking legal action because sex discrimination in pay is illegal in the United States.

Overpayment Inequity

What would you do if you felt you were over-rewarded? In other words, how would you feel if you were the new employee in our student-worker scenario? Originally, equity theory proposed that over-rewarded individuals would experience guilt and would increase their effort to restore perceptions of equity. However, research does not provide support for this argument. Instead, it seems that individuals experience less distress as a result of being over-rewarded (Austin & Walster, 1974). It is not hard to imagine that individuals find perceptual ways to deal with a situation like this, such as believing they have more skills and bring more to the situation compared to the referent person. Therefore, research does not support equity theory’s predictions with respect to people who are overpaid (Evan & Simmons, 1969).

Individual Differences in Reactions to Inequity

So far, we have assumed that once people feel a situation is inequitable, they will be motivated to react. However, does inequity disturb everyone equally? Researchers have identified a personality trait that explains different reactions to inequity and named this trait as equity sensitivity (Huseman, Hatfield, & Miles, 1987). Equity-sensitive individuals expect to maintain equitable relationships, and they experience distress when they feel they are over-rewarded or under-rewarded. At the same time, there are some individuals who are benevolents, those who give without waiting to receive much in return, and entitleds, who expect to receive substantial compensation for relatively little input. Therefore, the theory is more useful in explaining the behavior of equity-sensitive individuals, and organizations will need to pay particular attention to how these individuals view their relationships.

Fairness Beyond Equity: Procedural and Interactional Justice

Equity theory looks at perceived fairness as a motivator. However, the way equity theory defines fairness is limited to fairness of rewards. Starting in the 1970s, research on workplace fairness began taking a broader view of justice. Equity theory deals with outcome fairness, and therefore it is considered to be a distributive justice theory. Distributive justice refers to the degree to which the outcomes received from the organization are perceived to be fair. Two other types of fairness have been identified: procedural justice and interactional justice.

 Dimensions of Organizational Justice

Let’s assume that you just found out you are getting a promotion. Clearly, this is an exciting outcome and comes with a pay raise, increased responsibilities, and prestige. If you feel you deserve to be promoted, you would perceive high distributive justice (your getting the promotion is fair). However, you later found out upper management picked your name out of a hat! What would you feel? You might still like the outcome but feel that the decision-making process was unfair. If so, you are describing feelings of procedural justice. Procedural justicerefers to the degree to which fair decision-making procedures are used to arrive at a decision. People do not care only about reward fairness. They also expect decision-making processes to be fair. In fact, research shows that employees care about the procedural justice of many organizational decisions, including layoffs, employee selection, surveillance of employees, performance appraisals, and pay decisions (Alge, 2001; Bauer et al., 1998; Kidwell, 1995). People also tend to care more about procedural justice in situations in which they do not get the outcome they feel they deserve (Brockner & Wisenfeld, 1996). If you did not get the promotion and later discovered that management chose the candidate by picking names out of a hat, how would you feel? This may be viewed as adding insult to injury. When people do not get the rewards they want, they tend to hold management responsible if procedures are not fair (Brockner et al., 2007).

Why do employees care about procedural justice? There are three potential reasons (Cropanzano, Bowen, & Gilliland, 2007; Tyler, 1994; Tyler, Degoey, & Smith, 1996). First, people tend to believe that fairness is an end in itself and it is the right thing to do. Second, fair processes guarantee future rewards. If your name was picked out of a hat, you have no control over the process, and there is no guarantee that you will get future promotions. If the procedures are fair, you are more likely to believe that things will work out in the future. Third, fairness communicates that the organization values its employees and cares about their well-being.

Research has identified many ways of achieving procedural justice. For example, giving employees advance notice before laying them off, firing them, or disciplining them is perceived as fair (Kidwell, 1995). Advance notice helps employees get ready for the changes facing them or gives them an opportunity to change their behavior before it is too late. Allowing employees voice in decision making is also important (Alge, 2001; Kernan & Hanges, 2002; Lind, Kanfer, & Earley, 1990). When designing a performance-appraisal system or implementing a reorganization, it may be a good idea to ask people for their input because it increases perceptions of fairness. Even when it is not possible to have employees participate, providing explanations to employees is helpful in fostering procedural justice (Schaubroeck, May, & William, 1994). Finally, people expect consistency in treatment (Bauer et al., 1998). If one person is given extra time when taking a test while another is not, individuals would perceive decision making as unfair.

Now let’s imagine the moment your boss told you that you are getting a promotion. Your manager’s exact words were, “Yes, we are giving you the promotion. The job is so simple that we thought even you can handle it.” Now what is your reaction? The feeling of unfairness you may now feel is explained by interactional justice. Interactional justice refers to the degree to which people are treated with respect, kindness, and dignity in interpersonal interactions. We expect to be treated with dignity by our peers, supervisors, and customers. When the opposite happens, we feel angry. Even when faced with negative outcomes such as a pay cut, being treated with dignity and respect serves as a buffer and alleviates our stress (Greenberg, 2006).

Employers would benefit from paying attention to all three types of justice perceptions. In addition to being the right thing to do, paying attention to justice perceptions leads to outcomes companies care about. Injustice is directly harmful to employees’ psychological health and well-being and contributes to stress (Greenberg, 2004; Tepper, 2001). High levels of justice create higher levels of employee commitment to organizations, and they are related to higher job performance, higher levels of organizational citizenship (behaviors that are not part of one’s job description but help the organization in other ways, such as speaking positively about the company and helping others), and higher levels of customer satisfaction. Conversely, low levels of justice lead to retaliation and support of unionization (Blader, 2007; Cohen-Charash & Spector, 2001; Colquitt et al., 2001; Cropanzano, Bowen, & Gilliland, 2007; Masterson, 2001; Masterson et al., 2000; Moorman, 1991; Skarlicki & Folger, 1997).

Influencing Expectancy Perceptions

Employees may not believe that their effort leads to high performance for a multitude of reasons. First, they may not have the skills, knowledge, or abilities to successfully perform their jobs. The answer to this problem may be training employees or hiring people who are qualified for the jobs in question. Second, low levels of expectancy may be because employees may feel that something other than effort predicts performance, such as political behaviors on the part of employees. If employees believe that the work environment is not conducive to performing well (resources are lacking or roles are unclear), expectancy will also suffer. Therefore, clearing the path to performance and creating an environment in which employees do not feel restricted will be helpful. Finally, some employees may perceive little connection between their effort and performance level because they have an external locus of control, low self-esteem, or other personality traits that condition them to believe that their effort will not make a difference. In such cases, providing positive feedback and encouragement may help motivate employees.

Influencing Instrumentality Perceptions

Showing employees that their performance is rewarded is going to increase instrumentality perceptions. Therefore, the first step in influencing instrumentality is to connect pay and other rewards to performance using bonuses, award systems, and merit pay. However, this is not always sufficient, because people may not be aware of some of the rewards awaiting high performers. Publicizing any contests or award programs is needed to bring rewards to the awareness of employees. It is also important to highlight that performance, not something else, is being rewarded. For example, if a company has an employee of the month award that is rotated among employees, employees are unlikely to believe that performance is being rewarded. This type of meritless reward system may actually hamper the motivation of the highest performing employees by eroding instrumentality.

Influencing Valence

Employees are more likely to be motivated if they find the reward to be attractive. This process involves managers finding what their employees value. Desirable rewards tend to be fair and satisfy different employees’ diverging needs. Ensuring high valence involves getting to know a company’s employees. Talking to employees and surveying them about what rewards they find valuable are some methods to gain understanding. Finally, giving employees a choice between multiple rewards may be a good idea to increase valence.

Reinforcement Interventions

Reinforcement theory describes four interventions to modify employee behavior. Two of these are methods of increasing the frequency of desired behaviors, while the remaining two are methods of reducing the frequency of undesired behaviors.

 Reinforcement Methods

Positive reinforcement is a method of increasing the desired behavior (Beatty & Schneier, 1975). Positive reinforcement involves making sure that behavior is met with positive consequences. For example, praising an employee for treating a customer respectfully is an example of positive reinforcement. If the praise immediately follows the positive behavior, the employee will see a link between the behavior and positive consequences and will be motivated to repeat similar behaviors.

Negative reinforcement is also used to increase the desired behavior. Negative reinforcement involves removal of unpleasant outcomes once desired behavior is demonstrated. Nagging an employee to complete a report is an example of negative reinforcement. The negative stimulus in the environment will remain present until positive behavior is demonstrated. The problem with negative reinforcement is that the negative stimulus may lead to unexpected behaviors and may fail to stimulate the desired behavior. For example, the person may start avoiding the manager to avoid being nagged.

Extinction is used to decrease the frequency of negative behaviors. Extinction is the removal of rewards following negative behavior. Sometimes, negative behaviors are demonstrated because they are being inadvertently rewarded. For example, it has been shown that when people are rewarded for their unethical behaviors, they tend to demonstrate higher levels of unethical behaviors (Harvey & Sims, 1978). Thus, when the rewards following unwanted behaviors are removed, the frequency of future negative behaviors may be reduced. For example, if a coworker is forwarding unsolicited e-mail messages containing jokes, commenting and laughing at these jokes may be encouraging the person to keep forwarding these messages. Completely ignoring such messages may reduce their frequency.

Punishment is another method of reducing the frequency of undesirable behaviors. Punishment involves presenting negative consequences following unwanted behaviors. Giving an employee a warning for consistently being late to work is an example of punishment.

Reinforcement Schedules

In addition to types of reinforcements, researchers have focused their attention on schedules of reinforcement as well (Beatty & Schneier, 1975). Reinforcement is presented on a continuous schedule if reinforcers follow all instances of positive behavior. An example of a continuous schedule would be giving an employee a sales commission every time he makes a sale. In many instances, continuous schedules are impractical. For example, it would be difficult to praise an employee every time he shows up to work on time. Fixed-ratio schedules involve providing rewards every nth time the right behavior is demonstrated. An example of this would be giving the employee a bonus for every tenth sale he makes. Variable ratio involves providing the reinforcement on a random pattern, such as praising the employee occasionally when the person shows up on time. In the case of continuous schedules, behavioral change is more temporary. Once the reward is withdrawn, the person may stop performing the desired behavior. The most durable results occur under variable ratios, but there is also some evidence that continuous schedules produce higher performance than do variable schedules (Beatty & Schneier, 1975; Cherrington & Cerrington, 1974; Saari & Latham, 1982; Yukl & Latham, 1975).

A systematic way in which reinforcement theory principles are applied is called Organizational Behavior Modification (or OB Mod) (Luthans & Stajkovic, 1999). This is a systematic application of reinforcement theory to modify employee behaviors in the workplace. The model consists of five stages. The process starts with identifying the behavior that will be modified. Let’s assume that we are interested in reducing absenteeism among employees. In step 2, we need to measure the baseline level of absenteeism. How many times a month is a particular employee absent? In step 3, the behavior’s antecedents and consequences are determined. Why is this employee absent? More importantly, what is happening when the employee is absent? If the behavior is being unintentionally rewarded (e.g., the person is still getting paid or is able to avoid unpleasant assignments because someone else is doing them), we may expect these positive consequences to reinforce the absenteeism. Instead, to reduce the frequency of absenteeism, it will be necessary to think of financial or social incentives to follow positive behavior and negative consequences to follow negative behavior. In step 4, an intervention is implemented. Removing the positive consequences of negative behavior may be an effective way of dealing with the situation, or, in persistent situations, punishments may be used. Finally, in step 5 the behavior is measured periodically and maintained.

Studies examining the effectiveness of OB Mod have been supportive of the model in general. A review of the literature found that OB Mod interventions resulted in 17% improvement in performance (Stajkovic & Luthans, 1997). Particularly in manufacturing settings, OB Mod was an effective way of increasing performance, although positive effects were observed in service organizations as well.
