Cultivating careers, not just jobs
Mars’ approach to talent reflects its generational mindset. “We want to recruit people to have a career, not just come for a couple of years and then go somewhere else. If that happens, we have not succeeded in our mission,” explains Weihrauch. “The company needs to grow – and we as Associates need to grow in this relationship.”
This commitment shows: 75% of the company’s leaders are developed internally. Mars refers to its employees as “Associates” (always written with a capital A), a deliberate choice to reflect partnership and shared growth.
Weihrauch himself began his career at the chewing gum brand Stimorol, then spent six years at Nestlé before joining Mars in 2000. Over two decades, he led various business units, including a purpose-driven transformation of its pet care division, before becoming “group” CEO in 2022.
The transition to the top role brought a shift in scope and responsibility. “The buck stops with you,” he says. He’s now accountable not just for results, but for the entire enterprise and its culture.
One of the biggest adjustments was moving from being a business unit leader to leading other business unit leaders. Thinking back to his first executive team meeting as CEO, Weihrauch remembers with a smile how his team seemed to make a conscious effort to signal to him that his new role would require some operational letting go.
Today, he measures success less by personal contribution and more by how effectively he enables teams, fosters alignment, and facilitates high-quality dialogue.
To maintain performance and trust, the leadership team regularly conducts “difficult decision drills,” where they practice open feedback and pause meetings to address behaviors and interpersonal dynamics.
Creating space for vulnerability has strengthened relationships. But balancing personal connections with performance expectations remains a challenge. Weihrauch maintains that as CEO, you must “put the company first” even if it means asking well-liked team members to move on when necessary.
“If you don’t live up to this responsibility about having the best leaders at all levels, who eventually is paying the price? The people below – the Associates that work for a leader who is not performing – will eventually pay the price.”
