Motivation is one of the essential components for the success of any organization. Various theories have emerged to explain what drives people to commit to their tasks, but few address the psychological aspect of justice as deeply as Equity Theory. Developed by John Stacey Adams in 1963, this theory places justice at the center of motivation, arguing that perceptions of equity directly influence individuals' engagement and performance.
1. The Concept of Justice in Equity Theory
In Equity Theory, justice is understood as the perception that the rewards (outputs) a person receives are proportional to the effort (inputs) they put in, compared to other individuals in similar situations. According to Adams (1965), people are constantly evaluating their contributions and rewards, comparing them to those of their peers. This perception of justice, or the lack thereof, has a direct impact on motivation.
Below is a basic graphical representation that illustrates the concept of equity according to Equity Theory:

2. Distributive Justice and Procedural Justice
The theory addresses two types of justice:
Distributive Justice: Refers to the perception of fairness in the distribution of rewards and resources. When employees perceive that the outputs they receive (salary, promotions, recognition) are proportional to their inputs (effort, skills, time), they experience a sense of distributive justice.
Procedural Justice: Beyond the distribution itself, people also consider whether the processes by which decisions are made are fair. This includes the transparency of reward policies and the consistency in applying these policies. Procedural justice is crucial for maintaining the perception of equity, even when the rewards themselves are not ideally distributed.
Comparison Between Distributive Justice and Procedural Justice
Type of Justice | Definition | Practical Example |
Distributive Justice | Perception of fairness in the distribution of rewards and resources. | Salaries and bonuses proportional to performance and contribution. |
Procedural Justice | Perception of fairness in decision-making processes. | Transparency in promotion criteria and performance evaluations. |

3. The Comparison Process: The Pursuit of Justice
Adams (1963) suggests that an individual's motivation is affected by the perception of justice in the workplace. People compare their input-output ratios with those of others in similar positions. When they perceive inequality, a sense of injustice arises, which can lead to various behaviors to restore balance. This pursuit of justice is fundamental to maintaining employee motivation and engagement.

4. Impact of Perceived Injustice on Motivation and Behavior
When employees perceive injustice, whether distributive or procedural, they may adopt different strategies to cope with the situation, such as:
Reducing Effort: Decreasing the amount or quality of work as a way to adjust the input-output ratio.
Increasing Rewards: Seeking salary renegotiations or other benefits.
Changing Perception: Altering the perception of inputs or outputs to justify the current situation.
Leaving the Organization: In extreme cases, the person may decide to leave the organization, seeking a fairer situation elsewhere.
Greenberg's (1987) research highlights that perceptions of injustice can lead to retaliatory behaviors, such as sabotage, absenteeism, and even the decision to seek opportunities in other organizations.
Impact of Perceived Injustice
Reaction to Injustice | Resulting Behavior |
Reducing Effort | Decreased productivity and work quality. |
Increasing Rewards | Renegotiation of salaries or seeking new benefits. |
Changing Perception | Subjective re-evaluation of the current situation. |
Leaving the Organization | Departure and search for new opportunities. |

5. Practical Implications: Promoting Justice in Organizations
To effectively apply Equity Theory, it is essential for managers to focus on creating and maintaining a just work environment. This can be achieved by:
Developing Transparent Policies: Establishing clear policies for rewards and promotions, ensuring that everyone understands the criteria involved.
Open Communication: Keeping employees informed about how reward decisions are made.
Regular Feedback: Providing continuous feedback on performance, highlighting how inputs are valued by the organization.
Ongoing Monitoring: Regularly assessing perceptions of equity within the organization to identify and address potential issues.
6. Conclusion
Adams' Equity Theory provides a powerful framework for understanding how justice, both distributive and procedural, impacts motivation in the workplace. When people perceive that they are treated fairly, they are more motivated and committed. In contrast, the perception of injustice can lead to a range of detrimental behaviors, from reduced effort to leaving the organization.
Therefore, for leaders and managers, the challenge is to ensure that justice is a core value in organizational practices, promoting an environment where everyone feels that their efforts are properly recognized and rewarded.
