Juan Carlos Guerra – WTW

For Juan Carlos Guerra, talent advisor for HWC LATAM in WTW, human resources is more than just a function—it’s a mission rooted in empathy, adaptability, and global understanding. Tasked with supporting nine distinct lines of business across 13 countries in Latin America, Guerra brings both strategic clarity and emotional intelligence to one of the most complex roles in any organization: aligning people with purpose in an ever-evolving landscape.

WTW (Willis Towers Watson) is a global advisory, broking, and solutions company that helps clients worldwide turn risk into a path for growth. With more than 45,000 employees serving over 140 countries and markets, WTW specializes in risk management, employee benefits, and talent solutions. The company operates across diverse geographies and markets in Latin America, requiring HR leaders like Guerra to navigate cultural, linguistic, and economic nuances with precision.

The complexity of change

In the current environment, where economic uncertainty and technological disruption are reshaping every industry, one of Guerra’s biggest challenges is managing change itself. A recent transformation project in one of WTW’s Latin American business lines illustrates this clearly. The service and operating models were restructured to improve client delivery and expand the company’s portfolio, but the transition has been anything but simple.

“The implementation has not been as smooth as we had thought,” Guerra admits. “So, we’ve had to step in with a change management project that will help teams adapt our new service and operation models. We’re also working to strengthen belief in the new strategy and demonstrate how it will benefit our clients and people.”

This hands-on approach exemplifies Guerra’s leadership philosophy: meet resistance not with pressure, but with patience and understanding. With so many cultures and personalities under his HR umbrella, Guerra views listening as a core competency.

“I’ve learned to really listen to comprehend, not just to respond,” he says. “You need to understand how people feel in the moment—even if they’re stressed or angry—and offer calm support. That’s what builds trust.”

The work isn’t just about managing resistance; it’s also about creating alignment. With HR professionals embedded in each country and Centers of Expertise supporting recruitment, compensation, and services, Guerra coordinates a matrixed team that functions across borders. It’s an orchestra of moving parts, and his role is to ensure the music stays in harmony—even during times of disruption.

Recruiting across borders

One of the biggest misconceptions about recruiting in Latin America, Guerra explains, is that challenges are uniform across the region. “In reality, every line of business is like supporting a separate company,” he says. “They differ in nature, competition, local economies—even the kinds of talent they require.”

This variability makes recruitment and retention highly situational. Some areas may experience high turnover or struggle to attract niche talent, while others remain stable. WTW relies on a Center of Expertise model to address these dynamics, allowing HR specialists to focus on specific business segments. This specialization helps recruiters deeply understand market needs and deliver candidates who are a true fit—not just on paper, but in practice.

For Guerra, retention begins with the experience a colleague has from day one.

“We aim to be a magnet for top talent by creating great candidate and colleague experiences,” he says.

That includes initiatives around inclusion, belonging, and wellbeing—values woven into WTW’s “One HR” approach. From development opportunities to strategic projects, Guerra’s team provides a dynamic environment for professional growth.

“At WTW, we care deeply about each other, our clients, and our communities. That sense of purpose is what keeps people engaged,” he says. “We’re not just offering jobs—we’re offering meaningful careers.”

That sentiment is personal for Guerra. His interest in HR was inspired by his father, who also worked in the field. “Ever since I was young, I’ve had a passion for helping people,” he says. Whether volunteering in retirement homes or working with children, he found fulfillment in service—and that calling has never wavered.

Building for the future

Guerra’s experience leading through change goes beyond strategy—it’s deeply operational. He recalls the project that first brought him to WTW: a massive benefits harmonization effort following the merger of Willis and Towers Watson. The Mexico office alone had five different employers under its umbrella, each with its own compensation structures and policies.

The goal? Zero additional cost and zero employee resignations.

Partnering with a strategic provider like Creel, García-Cuéllar, Aiza & Enríquez – a leading full-service corporate law firm in Mexico, Guerra designed a labor strategy to navigate through the project; the goal was met—even in the face of major disruptions. First, a proposed merger with a competitor added uncertainty. Then the global pandemic hit just as implementation was set to begin. “We had contracts ready to sign and meetings scheduled, and suddenly we had to pause and rethink everything,” Guerra recalls.

The project was eventually completed virtually, with the same goals intact. “Not a single colleague resigned, and we achieved cost neutrality,” he says. “That was a huge success. It required incredible change management and reinforced the importance of a unified culture.”

Looking ahead, Guerra is focused on expanding the change management program over the next two years. The initiative will involve a series of mini-projects designed to improve adaptation, communication, and consistency across teams. These efforts aim to position WTW not just as a resilient organization, but as a forward-thinking one.

He also recognizes the potential of technology—especially AI—in optimizing HR services. AI can create new efficiencies from resume screening and onboarding to performance management and document workflows. But Guerra draws a firm line between automation and human connection.

“AI can support us, but it will never replace the human part of HR,” he says. “Personal interaction is irreplaceable. Data may inform decisions, but they are made by people.”

That belief in the irreplaceable value of human connection is at the core of Guerra’s leadership. It’s reflected in how he manages his time, builds teams, and approaches challenges. Even when processes slow or approvals get stuck—one of the most frustrating parts of his job—he finds satisfaction in the continuous learning his role brings.

“I’ve always had opportunities to work on different cases and projects,” he says. “It’s never static. That keeps me motivated.”

Guerra trusts and works side by side with Talent Sinergia Humana y Empresarial, another of his strategic allies, with whom he creates and works on development plans for C-level executives and their management teams, team building, executive coaching and change management.

Outside the office, Guerra is just as active. A sports enthusiast, he enjoys biking and long-distance swimming. Family is also central to his life—he’s married with two children and remains close with his parents and brother.

It’s this balance of discipline, empathy, and personal drive that defines Guerra’s approach to HR leadership. In a region as complex and dynamic as Latin America, those qualities aren’t just nice to have—they’re essential.

And as WTW continues to grow, adapt, and invest in its people, Guerra will be there—listening, guiding, and helping to ensure that behind every business goal is a human story worth supporting.
