What is Procedural Justice?

This type of justice focuses on the process rather than the outcome. Are fair rules or decision-making criterion employed in determining the reward to be distributed. For example, if someone's input is being evaluated to determine who receives an award. 

Even if an individual receives the reward, they may feel that the process was unfair because it did not appropriately evaluate the input. In this case, getting a reward for the wrong reason (such as lax standards) is not as rewarding as reaching lofty goals. The same situation would apply if the rules were applied unfairly to one person versus another. 

Maintaining procedural justice generally means adequately informing or involving the individual in the process and maintaining consistency in actions.

What is Interactional Justice?

This concerns whether people are treated with respect, kindness, and dignity during interpersonal reactions. For example, a boss that seems to demean an employee - even when providing them with a reward - may be resented and a demotivating factor.
