The Cambridge Business English Dictionary defines resilience as the quality of being able to return swiftly to a previous good condition after encountering problems. It signifies maintaining operations that are functional and growing. Even when confronted with challenges beyond control, such as economic shifts, global crises, or significant changes in the market.
For OCS, resilience is not a concept; it is a reality. It is 125 years of Facilities Evolution, from a one-man window cleaning business to a multi-billion-pound international organisation. Our journey has been shaped by adaptation, reinvention and endurance. We have worked through world wars, economic recessions, a global pandemic, and now face a future shaped by climate change, social needs and technological disruption.
To have not just survived but grown through these moments shows that resilience is part of who we are. It is embedded in our DNA.


The strength that keeps services moving
In today’s world, resilience involves not only recovering from setbacks but also being well-prepared, vigilant, and thoughtful. It cultivates an environment in which individuals can excel, even amidst high demands and limited time. This form of strength is practical and experienced, rather than merely theoretical.
Colleagues demonstrate resilience each time they report a hazard, raise a concern, support a teammate, or make a thoughtful decision. These actions protect safety, reinforce culture, and build trust with customers and communities.


Six connected pillars that bring resilience to life
OCS Resilience Week is shaped by six practical pillars. Together, they define how resilience is supported across our services, systems and teams:
QHSE – Stay Safe: Resilience is built through safe decisions, empowered by the confidence to pause, assess risk and act with care in every environment.
Wellbeing – Support Each Other: Resilience begins with the confidence to check in, supported by tools, time and trusted networks that help people care for themselves and others.
Safecall – Speak Up: Building resilience starts with the confidence to speak up and a trusted process that protects people, upholds values and prevents harm.
Risk – Think Smart: Resilience grows when people stay alert, trust their judgement and act early to identify and address potential risks before they escalate.
ESG – Reduce Impact: Resilient organisations make purpose-led decisions that balance performance with long-term environmental, social and ethical responsibility.
Cyber – Protect Data: Resilience in the digital world depends on everyday vigilance, where simple, safe habits help protect information, people and trust.


Resilience begins with our people.
Resilience is not merely about surviving; it is about adapting and thriving. The strength of OCS resides in the adaptability, commitment, and determination of our people. From expanding beyond window cleaning in the 1930s to becoming an international business in the 1960s, and transforming again through the 2023 merger with Atalian Servest, one constant has remained: our resilience is driven by the quality of our colleagues.
We are now a team of over 130,000 people. Many of our colleagues face personal challenges but still find the strength to carry on, deliver essential services and support those around them. That human resilience is at the heart of everything we do.
Shaping the future with a shared vision
In 2024, OCS launched a refreshed brand strategy centred on delivering the best experiences, productivity, practices, resilience, and outcomes for our colleagues, customers, and communities. These five BEST pillars help guide our response to global challenges such as climate risk, digital change, labour availability, and inclusion.
Our TRUE values of Trust, Unity, Respect, and Empowerment translate strategy into action. They cultivate a culture where colleagues are prepared to lead through uncertainty and change. When individuals feel trusted, valued, and empowered, they are more likely to step forward and assist others.
Resilience also entails looking forward. By cultivating awareness and investing in knowledge, we equip our colleagues to respond more effectively. This approach shifts us from reacting to anticipating. It enables us to prepare for challenges such as environmental disruption, technological acceleration, and economic volatility. In every instance, our strength begins with people.
Every safe action, every thoughtful choice and every conversation that encourages someone else to speak up makes a difference.
