Mastering equity theory: A brief guide

No one wants a job where they feel treated unfairly. When that happens, motivation and team morale drop fast. However, staff work harder when they feel treated fairly for their effort. This idea is the base of the equity theory of motivation.

So this theory is key to knowing what drives your staff. In turn, it shows how fairness shapes the whole company.

What is equity theory, and why does it matter at work?

Equity theory says people stay motivated when the rewards they get match the effort they put in, judged against what others receive.

In short, here is why it matters:

• Fair treatment lifts motivation and effort.
• Unfair pay or perks lowers morale fast.
• Staff compare their inputs and outputs to their peers.

What is equity theory?

The equity theory of motivation says employees are more motivated when their inputs, or efforts, are paid fairly. In contrast, they lose motivation when their inputs beat their outputs, or rewards.

This theory rests on a simple belief. People care about fairness, so they work harder when conditions feel fair. For example, say employees A and B do the same work in the same role. However, A gets paid more than B. As a result, B’s motivation drops.

In short, equity theory ties fairness to motivation. So the fairer something feels, the more driven a person becomes. Because of this, fairness also shapes employee engagement across the team.

Basic principles of equity theory

The equity theory works on inputs and outputs. In short, it is a give-and-take balance.

Inputs

Inputs are the effort an employee puts into their work. For example, this covers the tasks they do and the initiative they take. It also counts intangible traits, such as loyalty and hard work.

So it all comes down to how much work a person puts in. It also depends on how well the company sees that work.

Outputs

On the other hand, outputs are the rewards a person gets for their input. For example, this includes pay raises and promotions. It also includes praise and recognition.

It is standard to reward staff who put in the work. So it makes sense that motivation is tied to higher output. Fair rewards can also lower employee turnover.

Factors that affect equity theory

Several factors change how people see inputs and outputs. So let’s look at the main ones.

Referent groups

When people judge fairness, they compare their situation to others. These are known as referent groups, or referents. In practice, people may make these comparisons on purpose or without thinking.

So there are four main types of referents people use:

• Self-inside – Comparing your situation to a past one in the same organization
• Self-outside – Comparing your situation to a past one in a different organization
• Other-inside – Comparing your situation to another person’s in the same organization
• Other-outside – Comparing your situation to another person’s in a different organization

Moderating variables

Moderating variables can shape how a person sees fairness. For example, these include their experience level or schooling.

Say a person has many years in the field. So they may compare themselves to peers in a different firm. In another case, two new hires often compare themselves to each other. As a result, both go through a similar start.

Importance of equity theory

Results are everything to a company. However, the only way to reach them is through motivated staff. So equity theory helps employers see what drives their people.

Furthermore, the theory helps set fairness for all staff. For example, no equity exists if everyone gets the same reward no matter their input. In contrast, equity grows when rewards match skill, experience, and effort. As a result, fair treatment also supports job satisfaction across the team.

Applications of equity theory

You can apply equity theory in many ways. Each way aims to keep staff treated fairly.

Fair compensation

Paying staff by skill and performance is already common. Still, remember to align your compensation plan to market rates. So a little market research goes a long way. As a result, you set fair and competitive pay. Strong compensation management keeps this consistent over time.

Communicate with your employees

Every employee has a different background and driver. So get to know them on a personal level. Then learn what they value most. As a result, you gain a clear idea of how to support each one.

Look out for signs of inequity

Staff may feel unfairly treated yet stay quiet about it. So keep an open mind and watch for the signs. For example, an employee may work less or show a change in attitude. As an employer, address these issues right away. Doing so helps you avoid deeper employee retention problems.

Frequently asked questions

Who developed the equity theory of motivation?

Psychologist John Stacey Adams developed equity theory in the 1960s. He studied how fairness shapes worker motivation. So the model is often called Adams’ equity theory.

How is equity theory different from expectancy theory?

Equity theory focuses on fairness between effort and reward. Expectancy theory focuses on whether effort will lead to a reward. So both study motivation, but from different angles.

How can managers use equity theory day to day?

Managers can keep pay and praise fair and consistent. First, set clear reward rules. Then explain how decisions are made. As a result, staff trust the process more.

What happens when employees feel underpaid?

When staff feel underpaid, motivation and effort often fall. Some may reduce their work to match the reward. Others may look for a new job. So fair pay helps prevent both.

Does equity theory apply to remote teams?

Yes, equity theory applies to remote and in-house teams alike. Remote staff still compare their pay and workload to peers. So clear, fair rewards matter just as much from a distance.
