Armstrong (2007) offers the following definition of fairness in reward:
“A fair reward system is one that operates in accordance with the principles of distributive and procedural justice.”
From this it’s clear that there are two aspects to fairness, with distributive justice referring to how individuals see the distribution of reward between themselves and others and procedural justice identifying the need for fairness in how the level of reward is determined. The important point to note from this is that fairness in reward is very much about how individuals perceive the level of reward they receive, against the skills and effort deployed and how it compares to others. This makes fairness hard to manage, although efforts to ensure equity, consistency and transparency help.
