The Swedish leadership culture, characterized by flat hierarchies and consensus (consensus), influences the relationship between the board and the Chief of Staff (CoS) in several ways. In this culture, open dialogue, participation, and collective decision-making are common rather than formal mentoring roles. If a specific board member is appointed to support the CoS, this should be done with respect for collective responsibility and transparency. The role should be designed to strengthen collaboration and trust rather than create informal power structures. It is important that all parties – board, CEO, and CoS – agree on the role’s purpose and boundaries. By building on openness and inclusion, the organization can benefit from supportive roles without compromising Swedish corporate governance practices or risking ambiguities regarding the division of responsibilities.
