HOUSE BILL NO.  3103 
Introduced by: REPRESENTATIVE ARNULF BRYAN “ARNIE” B. FUENTEBELLA 
EXPLANATORY NOTE 
Sec. 18 of the Art. II of the 1987 Philippine Constitution states that: 
“Section 18. The State affirms labor as a primary social 
economic force. It shall protect the rights of workers and 
promote their welfare” 
This bill seeks to acknowledge the pernicious effects of climate change on 
our workforce, which has suffered rising temperatures, heavy rains, and erratic 
weather patterns, all of which affects various aspects of labor: their physical 
wellness, their travel to work, and the performance of professional duties, among 
others. Though the Department of Labor and Employment has done a 
commendable job of addressing these issues piecemeal through labor advisories, 
hazards wrought by climate change have yet to be realized in national legislation.  
Heat stress, for example, is now a worldwide phenomenon which causes 
undesirable physiological effects, such as heat strokes, exhaustion, cardiovascular 
diseases, kidney diseases, and respiratory conditions. This especially affects 
sectors the economic activities of which are conducted outside airconditioned 
areas, which include farming, fishing, and construction work. Productivity is also 
affected, which affects the country’s economy. 
By expressly identifying climate change as a real risk to our workforce, 
employers – the government included – can make the necessary adjustments to 
keep the workplace safe for employees. Through this legislation, I seek to fully 
recognize the effects of climate change vis-à-vis labor and to adopt data-driven 
solutions for subsequent policies to alleviate the plight of the Filipino worker. 
In view of the foregoing, the passage of this bill is earnestly sought.
