Introduction

The recent closure of Heathrow Airport due to a power outage has highlighted critical lessons for HR professionals across various industries. On March 21, 2025, a fire at an electrical substation led to an unprecedented 18-hour shutdown of one of the world's busiest airports, causing widespread disruptions and financial losses estimated in hundreds of millions of pounds[1][3]. This event underscores the importance of business continuity planning, effective communication, and employee management during crises. HR teams play a pivotal role in navigating such challenges, and here’s what they can learn:

Business Continuity Planning

Effective business continuity planning is essential for organisations to mitigate the impact of unforeseen events. HR should ensure that employees are trained and aware of their roles during emergencies, fostering an environment where contingency plans are regularly rehearsed and updated. According to Ruth Cornish, founder of Amelore, HR should focus on three clear levels of planning:

• Gold (strategic control and command),
• Silver (tactical coordination),
• Bronze (operational execution), with a senior HR lead playing a crucial role in activating resources during crises[1].

In the case of Heathrow, while the airport had backup power supplies, transitioning between different power sources proved challenging. This highlights the importance of seamlessly integrating backup systems and ensuring that critical infrastructure remains operational during disruptions[1].

Communication Strategies

Clear communication is vital for maintaining operational stability during emergencies. HR must ensure that all employees understand their responsibilities in both normal operations and crisis scenarios. This includes proper messaging about the crisis situation, the roles employees should play, and how these roles differ from standard operations[1].

For instance, during the Heathrow closure, passengers and employees alike needed constant updates about the status of operations and any available services. Employers must maintain transparency and offer support, such as alternative transport arrangements or accommodation for stranded employees[2].

Managing Employee Disruptions

When disruptions like the Heathrow closure occur, many employees may find themselves stranded or unable to attend work. Employers have a duty of care, particularly for business travelers, and should offer flexibility in managing leave and ensuring that employees can return home safely.

Key Considerations for HR:

• Flexibility in Leave Management: Allow employees to adjust their leave plans or provide options for paid/unpaid leave to cover extended absences.
• Communication: Ensure employees can easily contact employers for updates or assistance.
• Support for Stranded Employees: Provide or assist with alternative travel arrangements and accommodations if necessary[2].

Business Interruption and Risk Management

The economic impact of the Heathrow closure was significant, affecting not only airport operations but also global supply chains and businesses reliant on air travel. HR teams should work closely with risk management departments to assess potential vulnerabilities and explore mitigating strategies like business interruption insurance.

Business Interruption Insurance Considerations:

• Coverage Types: Understand what types of disruptions are covered (e.g., utility service interruptions).
• Policy Review: Regularly assess existing insurance policies to ensure they address indirect risks like supply chain disruptions.
• Mitigating Financial Losses: Implement comprehensive insurance plans to protect against unforeseen events[3].

Conclusion

The Heathrow Airport closure serves as a stark reminder of the need for robust business continuity planning, effective communication, and proactive employee management during crises. HR professionals must be at the forefront of these efforts, ensuring that organisations are prepared to face unexpected disruptions and maintain operational resilience.
