In De La Salle Araneta University vs. Bernardo [G.R. No. 190809, February 13, 2017], the Supreme Court ruled:
Republic Act No. 7641 states that “any employee may be retired upon reaching the retirement age x x x;” and “[i]n case of retirement, the employee shall be entitled to receive such retirement benefits as he may have earned under existing laws and any collective bargaining agreement and other agreements.” The Implementing Rules provide that Republic Act No. 7641 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, except to those specifically exempted x x x.” And Secretary Quisumbing’s Labor Advisory further clarifies that the employees covered by Republic Act No. 7641 shall “include part-time employees, employees of service and other job contractors and domestic helpers or persons in the personal service of another.”
The only exemptions specifically identified by Republic Act No. 7641 and its Implementing Rules are: (1) employees of the National Government and its political subdivisions, including government-owned and/or controlled corporations, if they are covered by the Civil Service Law and its regulations; and (2) employees of retail, service and agricultural establishments or operations regularly employing not more than 10 employees.
Based on Republic Act No. 7641, its Implementing Rules, and Secretary Quisumbing’s Labor Advisory, Bernardo, as a part-time employee of DLS-AU, is entitled to retirement benefits. The general coverage of Republic Act No. 7641 is broad enough to encompass all private sector employees, and part-time employees are not among those specifically exempted from the law. The provisions of Republic Act No. 7641 and its Implementing Rules are plain, direct, unambiguous, and need no further elucidation. Any doubt is dispelled by the unequivocal statement in Secretary Quisumbing’s Labor Advisory that Republic Act No. 7641 applies to even part-time employees.
Under the rule of statutory construction of expressio unius est exclusio alterius, Bernardo’s claim for retirement benefits cannot be denied on the ground that he was a part-time employee as part-time employees are not among those specifically exempted under Republic Act No. 7641 or its Implementing Rules.
