Wages are paid to blue-collar workers like manual laborers on a daily or weekly basis for work where value can be easily quantified monetarily, while salary is paid monthly to white-collar employees such as executives and managers whose contributions are more difficult to measure precisely. Compensation includes wages as well as benefits, leave, facilities, travel allowances, housing, rank privileges, and non-monetary awards to achieve objectives like ensuring fair pay, attracting and retaining quality employees, balancing compensation with work, and boosting morale.
