Money promised to an employee in addition to the monthly salary, hourly wage, commission or piece rate usually due as compensation. Bonuses are in addition to any other remuneration rate and may be predicated on performance over and above that which is paid for hours worked, pieces made, or sales completed. A bonus may be in the form of a gratuity where there is no promise for their payment, for example, a holiday bonus at the end of the year. Additionally, a bonus may be a contractually required payment where a promise is made that a bonus will be paid in return for a specific result, such as exceeding a minimum sales figure or piece quota, or as an inducement to remain in the employ of the employer for a certain period of time. Sums earned as bonuses are wages under the definition found in Labor Code Section 200.
