MANILA, Philippines — The Metropolitan Manila Development Authority (MMDA) will implement a four-day work week for personnel assigned to its main building in Pasig City starting Monday as part of energy conservation measures amid the ongoing conflict in the Middle East, the agency announced Saturday. The new work arrangement, contained in MMDA Memorandum Circular 05, Series of 2026, follows a directive from President Ferdinand Marcos Jr. to reduce electricity and fuel consumption across government offices. Under the scheme, covered employees will work 10 hours a day from Monday to Thursday to complete the required 40 working hours per week, in accordance with Civil Service Commission policies on alternative work arrangements. The prescribed office hours will be 7 a.m. to 6 p.m. Friday, Saturday and Sunday will serve as non-working days or rest days for employees covered by the scheme. The MMDA said the arrangement would apply only to officials and employees performing support and administrative functions at the MMDA New Building in Pasig City, while personnel assigned to essential, field, operational and emergency response functions outside the main building will not be covered. As part of the changes, the agency will temporarily suspend shuttle services to distant routes, including PITX, Lawton, Sta. Lucia, MCU Monumento and Fairview. However, a limited shuttle route between the MMDA main building along C-5 in Pasig City and EDSA near SM Megamall will continue to operate. MMDA Chairman Don Artes said the agency would ensure that public services remained uninterrupted despite the new work schedule. The memorandum will remain in effect until further notice or until revoked by the President, the MMDA said.
