(UPDATE) THE Metropolitan Manila Development Authority (MMDA) will implement a four-day workweek 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 on Saturday. The new work arrangement, cited 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 daily, Monday through 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 be nonworking days (or rest days) for employees covered by the scheme. The MMDA said the arrangement applies only to officials and employees performing support and administrative functions at the MMDA New Building in Pasig City, and personnel assigned to essential, field, operational and emergency response functions outside the main building are not covered. As part of the changes, the agency will temporarily suspend shuttle services to remote destinations, including PITX, Lawton, Santa 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 will ensure that public services remain uninterrupted despite the new work schedule. The memorandum will remain in effect until further notice or until revoked by the president, the MMDA said.
