⚖️ Adams'' Equity Theory

Big Idea: People compare their inputs (effort, skills, time) and outputs (pay, recognition, promotion) to those of others. If the ratio feels unfair, they become demotivated.

  • Inputs = what the employee gives: effort, experience, skills, qualifications, time
  • Outputs = what the employee receives: salary, bonus, recognition, promotion, benefits
  • If my input/output ratio = your input/output ratio — I feel EQUITY (fair)
  • If I give more but get the same as you — I feel INEQUITY (unfair, demotivated)
  • If I give less but get more than you — I may feel guilt (over-rewarded)

How employees respond to inequity

  • Reduce effort (work less hard to match perceived unfairness)
  • Demand more pay or recognition
  • Change their comparison person (compare to someone else instead)
  • Leave the organization (turnover increases)
  • Rationalize the situation (convince themselves it is fair)
Equity theory explains why pay transparency and fair reward systems matter. If employees discover a colleague earns more for the same work, motivation drops sharply.
