This document discusses equity theory and organizational justice. Equity theory, proposed by John Stacy Adams, compares an employee's job inputs and outcomes to other employees' inputs and outcomes. There are three situations in equity theory: output is less than other outputs resulting in underreward inequality; output equals other outputs resulting in equality; and output is greater than other outputs resulting in overreward inequality. Organizational justice includes distributive justice relating employee efforts to incentives, procedural justice giving employees a chance to communicate about evaluation processes, informational justice keeping employees informed about decisions, and interpersonal justice reflecting respectful treatment between managers and employees.
