By The Department of Labor and Employment (DOLE) issued new guidelines on Tuesday, 27 October 2026, clarifying which work-related heat illnesses may be covered by compensation and what employers must do to protect workers during El Niño and other periods of extreme heat. The rules, contained in Labor Advisory No. 20, Series of 2026, require employers to implement control measures based on Heat Index categories and to track workplace heat illnesses while helping affected employees or their families file for state compensation, according to the Daily Tribune.
Labor Secretary Francis N. Tolentino issued the advisory pursuant to the Labor Code of the Philippines. It covers indoor and outdoor workers in private and public sectors enrolled in the Employees’ Compensation Program (ECP) through the Social Security System (SSS) or the Government Service Insurance System (GSIS), according to Explained PH. The advisory lists heat stroke, heat cramps, heat exhaustion, heat syncope, heat rash, rhabdomyolysis, dehydration-linked kidney damage, neurological disorders, and muscle injuries as compensable conditions. Workers can still claim benefits for unlisted heat illnesses if they can prove working conditions directly increased their risk of getting sick.
What the new compensation rules change
The guidelines expand the range of heat-induced conditions that may qualify for compensation beyond what many employers and workers previously understood as covered. Explained PH reported that authorities may consider job duties, workplace conditions, duration and intensity of heat exposure, protective equipment, and preventive measures to determine whether an illness is work-related. PAGASA heat index classifications may serve as supporting evidence of workplace heat conditions.
The advisory was issued alongside Employees’ Compensation Commission Board Resolution No. 26-10-40, Series of 2026. This matters because compensation claims run through the ECP, not through a separate DOLE fund. Private sector workers file through SSS; government workers file through GSIS. The practical effect is that employers must now treat heat illness documentation with the same seriousness as other occupational injury records. Employers must maintain occupational health records, work schedules, temperature logs, and witness statements to support claims. A construction worker who collapses from heat stroke on a 44-degree afternoon, a farm worker with heat cramps, or a delivery rider with heat exhaustion all fall within the categories the advisory names. PhilNews reported that these outdoor workers may be especially vulnerable.
Employer obligations under the Heat Index categories
The advisory sets four Heat Index categories with escalating employer duties. Under Caution (27 to 32 degrees Celsius), employers must provide drinking water, shaded or ventilated work areas, light-colored and breathable clothing, hydration reminders, and heat stress training. Under Extreme Caution (33 to 41 degrees Celsius), employers must enforce structured work, rest and hydration cycles; establish cool-down areas; implement peer monitoring; provide personal protective equipment; schedule strenuous tasks during cooler hours; and ensure access to trained occupational safety and health first-aiders.
Under Danger (42 to 51 degrees Celsius), employers must implement flexible work arrangements or telecommuting. Under Extreme Danger (52 degrees Celsius and above), employers may be required to suspend, relocate, reschedule or substantially modify work operations. These thresholds align with the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) heat index classifications. Employers must monitor PAGASA advisories on El Niño, seasonal climate outlooks, Heat Index information and observed Heat Index data. Hazard identification, risk assessment and control (HIRAC) assessments must be reviewed and updated periodically based on PAGASA information.
How this connects to existing prevention rules
The new advisory builds on DOLE Labor Advisory No. 8, Series of 2023, which established safety and health measures to prevent and control heat stress at the workplace. That earlier advisory, discussed in a DOLE Bureau of Working Conditions webinar, cited Article 168 of the Labor Code, which requires employers to provide a safe and healthful working environment. The 2023 rules focused on prevention: engineering controls such as ventilation, insulation, shielding from radiant heat, air conditioning, and local exhaust ventilation, plus administrative controls such as work-rest cycles, scheduling hot tasks for cooler hours, acclimatization, buddy systems, and dress code adjustments.
The 2026 advisory adds a compensation layer that the 2023 rules did not address. Neither the 2023 advisory nor the DOLE webinar covered specific compensation amounts, filing deadlines, or claim procedures. The new advisory requires employers to ensure workers are enrolled in the SSS and that contributions are paid, which is a precondition for ECP eligibility. Workers who develop symptoms linked to workplace heat exposure should seek medical attention and check with government offices about eligibility under the ECP. The advisory does not, based on the available reports, specify new benefit amounts or formulas. Compensation likely follows existing ECP schedules under Presidential Decree No. 626, but readers should confirm current rates with SSS or GSIS.
What HR and payroll teams should do now
HR teams should treat the advisory as a compliance checklist rather than a suggestion. The first step is to review current heat stress controls against the four Heat Index categories and document any gaps. Payroll teams should verify that all employees, including project-based and seasonal workers, have active SSS or GSIS coverage and that contributions are current. A worker without active coverage cannot access ECP benefits, and the employer may face liability for the gap.
Documentation is the second priority. The advisory requires employers to maintain occupational health records, work schedules, temperature logs, and witness statements. These records support both prevention and compensation claims. If a worker reports heat cramps or heat exhaustion, the employer should record the date, time, Heat Index, work location, and any first aid provided. This documentation becomes evidence if the worker later files an ECP claim.
The third priority is training. The advisory requires heat stress training under the Caution category, but training should also cover how to recognize heat illness symptoms and how to report them. Heat cramps present as muscle pain and excessive sweating. Heat exhaustion presents as dizziness, weakness, and nausea. Heat stroke presents as confusion, extremely high body temperature, and possible loss of consciousness, and is a medical emergency. Supervisors should know the difference and know when to call for medical help.
Employers should also note that the advisory applies to indoor workers. The DOLE webinar identified indoor heat risks such as poorly maintained air conditioning, glass windows exposed to direct sunlight, server rooms, and prolonged power outages. A call center agent in a server room with broken cooling or an office worker near unshaded glass during a heat wave may have a compensable claim if working conditions directly increased their risk of illness. The advisory’s hazard assessment language explicitly includes ventilation and cooling reliability, power interruptions, and dust or smoke exposure as factors to consider.
The advisory does not state a retroactive effective date in the available reports. Employers should treat it as applying to heat illnesses that occur after issuance, but workers with pending claims for earlier illnesses should check with SSS or GSIS about eligibility. The advisory also does not specify penalties for non-compliance, but failure to implement required controls could expose employers to enforcement under Republic Act No. 11058, the Occupational Safety and Health Standards Law.
