Dennis was a taxi driver who was being paid on the "boundary" system basis. He worked tirelessly for Cabrera Transport Inc. for fourteen (14) years until he was eligible for retirement. He was entitled to retirement benefits. During the entire duration of his service, Dennis was not given his 13th month pay or his service incentive leave pay.

(a) Is Dennis entitled to 13th month pay and service incentive leave pay? Explain.
(b) Since he was not given his 13th month pay and service incentive leave pay, should Dennis be paid upon retirement, in addition to the salary equivalent to fifteen (15) days for every year of service, the additional 2.5 days representing one-twelfth (1/12) of the 13th month pay as well as the five (5) days representing the service incentive leave for a total of 22.5 days? Explain. (2012 BAR)
