Father Saturnino Urios University, Inc. vs. Atty. Ruben B. Curaza

Part-time employees in the private sector are entitled to retirement benefits under Republic Act No. 7641 upon reaching the age of sixty (60) and completing at least five (5) years of service, as the law does not exempt them and explicitly covers all employees irrespective of their position, designation, or employment status.

Father Saturnino Urios University hired Atty. Ruben B. Curaza in the second semester of school year 1979-1980 to teach commercial law, subsequently assigning him teaching loads across the College of Engineering, College of Arts and Sciences, and College of Law. He was engaged strictly as a part-time instructor, compensated monthly on a per-hour, per-teaching-load, and per-semester basis, without ever attaining permanent or regular status. After turning sixty and submitting a retirement application in November 2008, the University denied his claim, citing its internal policy of excluding part-time teachers from retirement benefits and arguing that Republic Act No. 7641 and the applicable Collective Bargaining Agreement did not cover him.

• Atty. Curaza was hired as a part-time instructor in 1979 and intermittently taught across multiple university departments, with his compensation calculated per teaching hour, per subject load, and per semester. He applied for early retirement in November 2008 upon reaching age 60, but the University's HR department denied the application, stating that part-time teachers were categorically excluded from retirement benefits under institutional policy. The University further argued that Atty. Curaza's employment was discontinuous, citing gaps in his teaching load during several academic years, and maintained that he did not qualify as a permanent employee under the Manual of Regulations for Private Schools. When the dispute reached the appellate courts, the University submitted a teaching load summary covering school years 1990-1991 to 2008-2009, which the Court of Appeals utilized to determine his creditable years of service.

• Petitioners contended that Republic Act No. 7641 does not apply to part-time instructors because they cannot acquire regular permanent status, which they argued is a statutory prerequisite for retirement benefits. They cited the Manual of Regulations for Private Higher Education and prior jurisprudence to assert that part-time faculty are explicitly excluded from permanent status and, consequently, from retirement coverage. Petitioners also challenged the computation of Atty. Curaza's service years, arguing that each semester's contract should be treated independently rather than cumulatively, and claimed that awarding damages was improper absent a finding of illegal dismissal.

• Respondent maintained that he satisfied the statutory requirements for retirement under Republic Act No. 7641 by reaching the age of sixty and rendering more than five years of service, regardless of his part-time classification. He relied on the October 24, 1996 Labor Advisory and the Implementing Rules of the Labor Code, which explicitly include part-time employees within the coverage of the Retirement Pay Law. He further argued that company policies, institutional manuals, and collective bargaining agreements cannot contravene or diminish statutory rights expressly granted by Congress to private sector employees.

• Procedural Issues: N/A
• Substantive Issues: Whether part-time faculty members in private educational institutions are entitled to retirement benefits under Republic Act No. 7641 despite lacking regular permanent status, and whether the Court of Appeals correctly computed the respondent's creditable years of service at 22 years.

• Procedural: N/A
• Substantive: The Court ruled that part-time employees are unequivocally covered by Republic Act No. 7641, as the statute's text applies to "all employees in the private sector, regardless of their position, designation or status and irrespective of the method by which their wages are paid." The Court applied the principle of expressio unius est exclusio alterius, noting that the law's enumerated exemptions (government employees and small retail/service/agricultural establishments) do not include part-time workers, thereby mandating their inclusion. The Court rejected the requirement of permanent status, emphasizing that statutory language prevails over administrative manuals, legislative deliberations, or institutional policies. On the computation of service years, the Court affirmed the 22-year figure, holding that periods with less than six months of teaching load were properly excluded, and the University was estopped from denying service for prior academic years because its own submitted evidence only covered 1990-1991 onwards.

• Expressio unius est exclusio alterius — The explicit mention of one thing implies the exclusion of others. Applied to determine that because Republic Act No. 7641 specifically enumerates exempted employee categories, all other private sector workers, including part-time faculty, are necessarily covered by the law.
• Estoppel — A party cannot deny a fact or assert a right contrary to its own prior conduct or evidence. Applied to preclude the University from disputing the respondent's years of service prior to 1990-1991, as the teaching load summary it voluntarily submitted as evidence only began in 1990-1991, implying continuous service for the preceding decade.

• "Republic Act No. 7641 specifically states that 'any employee may be retired upon reaching the retirement age[,]' and that in case of retirement, in the absence of a retirement agreement, an employee who reaches the retirement age 'who has served at least five (5) years... may retire and shall be entitled to retirement pay[.]' No exception is made for part-time employees." — Emphasizes the unambiguous statutory coverage of all private sector employees.
• "The exclusion of non-permanent employees from the coverage of Republic Act No. 7641 has no legal basis." — Clarifies that permanent employment status is not a statutory prerequisite for claiming retirement benefits under the law.

• De La Salle Araneta University v. Bernardo — Cited as controlling precedent establishing that Republic Act No. 7641 covers all private sector employees except those specifically exempted, and confirming that part-time employees qualify for retirement benefits.
• Lacuesta v. Ateneo de Manila University and UST v. NLRC — Cited by petitioners to argue that the Manual of Regulations for Private Schools governs faculty permanency status, but distinguished by the Court as administrative guidelines that cannot override the explicit statutory mandate of the Retirement Pay Law.

• Republic Act No. 7641 (Retirement Pay Law) — The primary statute granting retirement benefits to private sector employees who reach age 60 with at least five years of service; interpreted to include part-time workers absent explicit statutory exemption.
• Book VI, Rule II, Sections 1 and 2 of the Rules Implementing the Labor Code — Defines the broad coverage of RA 7641 and enumerates specific exemptions, explicitly including part-time employees while excluding only government workers and small establishments.
• Labor Advisory dated October 24, 1996 (Guidelines for the Effective Implementation of RA 7641) — Clarifies that statutory coverage "shall include part-time employees, employees of service and other job contractors and domestic helpers," reinforcing that company policies cannot diminish statutory retirement rights.
• Section 117 of the Manual of Regulations for Private Higher Education of 2008 — Cited by petitioners to assert that part-time teachers cannot attain permanent status, but deemed insufficient to override the comprehensive coverage mandate of RA 7641.
