Labour Day spotlight: Climate Change threatens worker health worldwide

By Vivek Saini

As the world grapples with escalating temperatures and intensifying climate-related disasters, the intersection of climate change and worker health emerges as a critical focal point. Recently, the International Labour Organization (ILO) released a report illuminating the profound impact of climate hazards on the global workforce. Beyond the discomfort of rising temperatures lies a more profound concern: the widespread health risks workers face across various sectors and regions. From the threat of heat stress to the exacerbation of respiratory illnesses due to deteriorating air quality, the report underscores the multifaceted challenges confronting workers today. Urgency permeates the narrative, driven by alarming statistics such as the staggering toll of heat stress-related deaths and the prevalence of chronic diseases among workers.

Heatstroke and Beyond: Climate Hazards Threaten Millions of Workers

The scorching heatwaves gripping various regions worldwide are not just uncomfortable; they are a stark reminder of the escalating threats climate change poses to workers. Beyond the discomfort and reduced productivity associated with rising temperatures, a new report by the International Labour Organization (ILO) paints a concerning picture: climate hazards are already a significant health risk for a vast portion of the global workforce. The “Ensuring Safety and Health at Work in a Changing Climate” report estimates that billions of workers are exposed to dangers amplified by climate change, including extreme heat, ultraviolet radiation, air pollution, and the frequency and intensity of natural disasters. These are not just potential risks; they are already causing significant harm, demanding immediate attention and action.

These hazards are not isolated incidents; they are global crises. Heat stress is a particular area of concern, and it alone is responsible for nearly 19,000 deaths and over 26 million cases of chronic kidney disease every year. This is not just a statistic but a call to action. It highlights the urgency of addressing this issue for worker safety and the long-term health of our global workforce. It’s a problem that affects us all, and we must all contribute to the solution.

The report further explores the impact of worsening air quality due to climate change. Increased wildfires and dust storms can exacerbate respiratory illnesses like asthma and Chronic Obstructive Pulmonary Disease (COPD). Rising ozone levels can also damage lung tissue and reduce lung function. These dangers are particularly concerning for outdoor workers, who are more likely to have prolonged exposure to these pollutants.

Climate change also contributes to the spread of vector-borne diseases. Warmer temperatures and altered weather patterns can create ideal breeding grounds for mosquitos and ticks, leading to a higher risk of diseases like malaria, dengue fever, and Lyme disease. This can disproportionately affect agricultural workers and those in geographically vulnerable areas. The ILO report serves as a wake-up call, urging us to acknowledge the growing threat climate change poses to worker health. It’s no longer a distant concern; it’s a present danger with potentially devastating consequences.

Global Threat, Unequal Burden: How Climate Change Affects Different Workers

Climate change is a global threat, but its impact on worker health is far from uniform. Certain professions and geographic locations face a significantly higher risk of health problems due to climate hazards. The ILO report, “Ensuring Safety and Health at Work in a Changing Climate,” emphasizes that outdoor workers are on the frontlines. This includes those in agriculture, construction, and other sectors where work primarily occurs outdoors. For instance, agricultural workers may face prolonged exposure to extreme heat, leading to heat stress and dehydration. On the other hand, construction workers may be at risk of heat-related illnesses due to the lack of shade and high physical exertion. These examples highlight the unique challenges different outdoor professions face and the urgent need for tailored solutions.

For example, a 2023 study published in the journal Environmental Health Perspectives found that agricultural workers in India experience significant health impacts due to rising temperatures. The study linked heat stress to increased rates of heatstroke and dehydration, potentially leading to chronic kidney disease. Workers in developing countries often face a double burden. Limited access to protective measures like cooling stations, proper clothing, and less robust healthcare systems can exacerbate health risks. Additionally, those in geographically vulnerable areas, like coastal communities or regions prone to floods and droughts, face additional risks associated with natural disasters.

The gender dimension of this issue cannot be ignored. Women often comprise a significant portion of the agricultural workforce globally. The ILO report acknowledges that gender inequalities in access to protective clothing, sanitation facilities, and healthcare can further disadvantage women. They may be less likely to access cooling measures or proper clothing and need more resources to seek medical attention for heat-related illnesses.

This uneven distribution of risks necessitates targeted solutions. Industries with high exposure risks must prioritize heat mitigation measures, such as providing proper shade and hydration breaks. Implementing flexible work schedules during extreme weather events and ensuring access to appropriate personal protective equipment (PPE) are crucial. Strengthening healthcare systems in vulnerable regions and ensuring equitable access to preventive care is critical for protecting workers’ health.

Protecting Our Workforce: Regulations, Adaptation, and the Road Ahead

The fight against climate change and its impact on worker health isn’t a solitary battle. The International Labour Organization (ILO) report emphasizes a multi-pronged approach. While the report paints a concerning picture of billions of workers facing extreme heat, worsening air quality due to rising ozone levels, and the increased frequency and intensity of natural disasters, it also proposes solutions.

Strengthening regulations is a crucial first step. Existing rules often need to address climate-related hazards adequately. Revisions must explicitly consider these dangers, potentially setting stricter exposure limits for heat and air pollutants and mandating heat mitigation measures for outdoor workplaces. This could involve ensuring workers access proper personal protective equipment (PPE) if exposed to harmful elements, like intense sunlight or extreme heat. Investing in adaptation strategies is another critical weapon in this fight. Early warning systems for extreme weather events can help prepare workplaces and workers for potential dangers. Heat-resistant infrastructure in workplaces and training programs on climate risks and heat stress prevention methods can further build resilience.

The report also highlights the importance of “social dialogue” – fostering collaboration between governments, employers, and worker organizations. Open communication and joint efforts are not just beneficial; they are essential. By working together, these stakeholders can develop effective policies and solutions to create a safe and healthy work environment in the face of climate challenges. Your role in this collaboration is crucial, and your input and efforts are highly valued.

Ultimately, fighting for worker health in a changing climate requires a collective effort. Governments must take the lead by implementing stricter regulations and investing in adaptation strategies. Employers must prioritize worker safety by incorporating heat mitigation measures and providing proper PPE. Finally, workers and their organizations play a crucial role in advocating for their health and safety by pushing for stronger regulations and participating in safety training programs. Working together can build a future where workplaces remain safe and healthy even as our climate changes.

The Road Ahead: Empowering Workers Through Knowledge

Climate change throws a complex curveball at worker safety, but the fight for a healthy workforce is far from over. The International Labour Organization (ILO) report, “Ensuring Safety and Health at Work in a Changing Climate,” outlines solutions that require a collaborative effort, a three-pronged attack from governments, employers, and worker organisations.

Governments as Protectors: Governments can set the bar high for worker safety. Here’s how they can lead the charge:

• Revamping Regulations: Existing regulations often need to catch up with climate hazards. Governments can revise them to explicitly address heat stress, worsening air quality (like rising ozone levels), and the increased frequency and intensity of natural disasters. This could involve setting stricter exposure limits and mandating heat mitigation measures for outdoor workplaces. 
• Investing in Resilience: Governments can play a crucial role in supporting the development and implementation of early warning systems for extreme weather events. Other impactful strategies include encouraging heat-resistant infrastructure projects and funding training programs on climate risks and heat stress prevention methods.

Employers as Champions of Safety: Employers are also responsible for prioritising worker safety in a changing climate. Here’s what they can do:

• Prioritizing Heat Mitigation: Outdoor workers must have shade, hydration breaks, and access to cooling technologies.
• Equipping with Proper PPE: Another crucial step is to equip workers with appropriate Personal Protective Equipment (PPE) to shield them from harmful elements like intense sunlight or extreme heat.
• Flexible Work Options: During extreme weather events, employers can consider flexible work schedules or temporary relocation of tasks indoors to minimize worker exposure to hazards.

Workers and Organizations: Active Participants: Workers and their organizations are not passive bystanders. They can be powerful advocates for their health and safety by:

• Building Knowledge: Actively seeking out and participating in training programs on climate risks and heat stress prevention methods empowers workers to protect themselves. Worker organizations can play a crucial role in facilitating this knowledge-building by providing training resources and advocating for worker participation in such programs. 
• Green Job Training Programs: Organizations like the International Labour Organization (ILO) and Green Jobs Alliance encourage the development of green job training programs that incorporate climate risk awareness and heat stress prevention methods. These programs can equip workers with the skills and knowledge to navigate a changing work environment.
• Demanding Change: Workers and their organizations can lobby governments to implement stricter regulations that protect workers from climate hazards. They can also hold employers accountable for prioritizing worker safety in a changing climate.
• Sharing Knowledge and Experiences: Workers who have experience working in hazardous climate conditions can share their knowledge and experiences with others. This can help raise awareness of potential risks and best practices for staying safe.

By working together, governments, employers, and worker organizations can create a future where workplaces are safe and healthy, even as our climate changes. This collaborative approach, with each stakeholder taking ownership and working towards the common goal, is the most effective way to build resilience and protect the health of the global workforce.
