Casual, seasonal employees ENTITLED to 13th month pay

OTHER PRINCIPLES ON 13TH MONTH PAY
[1] “Basic salary” or “basic wage” contemplates work within the normal eight (8) working hours in a day. This means that the basic salary of an employee for purposes of computing the 13th month pay should include all remunerations or earnings paid by the employer for services rendered during normal working hours.
[2] For purposes of computing the 13th month pay, “basic salary” should be interpreted to mean not the amount actually received by an employee, but 1/12 of their standard monthly wage multiplied by their length of service within a given calendar year.
[3] Extras, casuals and seasonal employees are entitled to 13th month pay.
