Compensation and remuneration include wages, salaries, incentives, fringe benefits, perquisites, and non-monetary benefits. Wage and salary administration establishes compensation policies and practices, covering job evaluation, wage surveys, analyzing organizational issues, developing wage structures, and controlling costs. The objectives are to attract qualified employees, reduce grievances, enhance motivation, and plan labor costs. Wage theories include reinforcement theory, equity theory, agency theory, marginal productivity theory, and surplus value theory to explain how compensation impacts employee performance and behavior.
