Extreme weather is no longer rare. It is a recurring operational condition. As we head into another record-breaking summer, the question is not if conditions will impact operations, but how prepared your organization is to perform under them.

Extreme heat is the most pervasive and often underestimated risk, often compounded by wildfire smoke, storms and infrastructure disruptions that affect both operations and workforce availability.

What may look like a series of isolated weather events is, in practice, a system-wide stress test on workforce availability and operational performance. Preparedness has shifted from protecting buildings to ensuring people and systems can operate under stress.

Recent data from the ILO shows that over 2.4 billion workers globally face extreme heat risks on the job. Extreme heat doesn’t just disrupt work — it degrades it. According to Health Action Alliance findings, at 90°F, productivity can drop by up to 25%, and above 100°F, it can fall by as much as 70%. Heat also increases workplace injuries, absenteeism and health care costs, contributing to an estimated $100 billion in annual economic losses in the U.S. alone.

For learning and development (L&D) leaders, this is a moment to step forward and help the organization get summer-ready: prepared for heat, smoke, storms and the real-world constraints employees face.

Below are three practical strategies to help leadership teams move from awareness to action.

Start Here: Understand What Breaks in the Summer

Before training begins, organizations need clarity on where summer conditions will impact performance — not just inside the workplace, but across the full system that enables people to show up and do their jobs.

Leaders should ask:

• Which assets and environments become unsafe or inefficient in heat or poor air quality?
• Which roles are most exposed?
• Where does productivity or accuracy break down?
• What systems fail first?

It’s also important to understand how summer conditions affect workforce readiness beyond the workplace:

• Who may not be able to get to work due to disruptions in commuting, childcare or local infrastructure?
• How are conditions affecting employees outside of work hours, including lack of cooling at home, poor overnight recovery, smoke exposure and increased caregiving demands?

These effects compound. Workers who cannot recover, travel safely or manage competing pressures at home are more likely to be absent, make mistakes or experience health impacts the following day.

Without this level of clarity, training remains generic. With it, organizations can prepare leaders to act on the real constraints their workforce faces — not just the conditions inside the workplace.

Strategy 1: Practice Real Decisions, Not Just Scenario

Most weather training is still a slide in an annual presentation. But in a real summer event, leaders don’t need reminders; they need to make decisions quickly and confidently, often with incomplete staffing and changing conditions.

The Goal: Move from awareness to decision-making under real conditions.

The Solution: Training should be grounded in specific, local scenarios tied to real thresholds:

• Define local risks (heat, smoke, storms and their combined effects)
• Use real thresholds, such as:
  • Heat index exceeds 95°F
  • Air quality reaches unhealthy levels
  • Power outages impact operations
• Incorporate workforce scenarios, such as:
  • 30% of staff unavailable due to childcare or transit disruptions
  • Employees unable to work outdoors due to heat or smoke exposure
  • Workers arriving fatigued due to overnight heat or poor air quality
• Run short decision exercises (30-minute simulations) where managers practice:
  • Adjusting schedules and workloads
  • Reassigning roles based on availability
  • Scaling or pausing operations safely
• Set clear triggers, for example:
  • “At 100°F, mandatory rest breaks and shift adjustments begin”
  • “At unhealthy air quality levels, outdoor work is limited or paused”

The key is knowing what to do when conditions and workforce capacity change simultaneously.

Strategy 2: Cross-Train Your Team So Work Doesn’t Stop

Extreme heat disrupts more than attendance. It affects who can work, where work can happen and how systems perform.

The Goal: Ensure critical operations continue even under stress.

Many organizations rely on a small number of people, locations or systems, creating vulnerabilities under stress.

How to do it:

• Identify “must-run” operations: What absolutely needs to continue each day?
• Cross-train critical roles so multiple people can perform essential functions
• Diversify coverage by training backups across geographies and living conditions to reduce correlated risk
• Plan for system and workforce stress, including:
  • Cooling or alternate workspaces
  • Indoor alternatives when outdoor work is unsafe
  • Adjusted shifts (early morning/evening)
  • Contingencies for power, transportation or supply disruptions

Strategy 3: Equip Managers to Lead Through Stress

During summer disruptions, employees are managing both work and significant personal strain.

The Goal: Enable managers to maintain performance while protecting people.

How leaders respond in these moments directly affects employee trust, retention and long-term performance.

How to do it:

• Train for situational leadership so managers can balance operational needs with safety and workforce realities
• Prioritize safety first: Ensure leaders know when to pause work, not push through
• Clarify flexibility tools, including emergency leave, adjusted expectations and remote options
• Encourage proactive check-ins, with regular communication during heat events, especially with vulnerable employees

Organizations that perform well under stress are those where employees know: “My safety is prioritized, and my manager understands what I’m dealing with.”

What Good Looks Like in Practice

High-performing organizations are already:

• Scheduling strenuous work during cooler hours
• Requiring hydration breaks every 15-20 minutes
• Providing cooling stations, shade or ventilation
• Adjusting operations based on air quality and heat thresholds
• Using buddy systems and regular supervisor check-ins
• Monitoring conditions and adapting in real time

These strategies can increase productivity, workforce stability and business continuity by protecting the safety of employees.

The Opportunity for L&D Leaders

Summer is not a neutral operating season. It is a predictable period of elevated risk and disruption.

Organizations that prepare will maintain productivity, reduce injuries and absenteeism, and stabilize workforce availability while others struggle to adapt.

This is where L&D can lead. Not by adding more training, but by equipping leaders to understand where risk shows up, make decisions under real-world constraints and align workforce readiness with operational demands.

In doing so, L&D moves beyond a support function to become a driver of performance and resilience, ensuring workforce preparedness that keeps the business running through summer disruption.
