Old English wedd, Gothic wadi "pledge"); see wed. Modern French cognate gages (plural) means "wages of a domestic," one of a plethora of French words for different classes, e.g. traitement (university professor), paye, salaire (workman), solde (soldier), récompense, prix.

Labour costs are not identical to wage and salary costs, because total labour costs may include such items as cafeterias or meeting rooms maintained for the convenience of employees. Wages and salaries usually include remuneration such as paid vacations, holidays, and sick leave, as well as fringe benefits and supplements in the form of pensions or health insurance sponsored by the employer. Additional compensation can be paid in the form of bonuses or stock options, many of which are linked to individual or group performance
