Boardroom voting blocs: A stumbling block to stakeholder success

By Mark Rogers, managing director and head of the Board Practice, Robert Half

Almost every experienced board member has encountered situations in which two or more directors consistently vote together on resolutions, regardless of the merits of the issue. Voting blocs can develop for a variety of reasons: loyalty among certain directors, tension or persistent disagreement with others, shared allegiance to particular shareholders, or even a subset of groupthink. Depending on their size, these blocs can centralize decision-making authority within a subset of the board, marginalize minority viewpoints, and curtail meaningful deliberation ahead of major votes. At best, voting blocs undermine good governance; at worst, they become a rubber stamp for a predetermined agenda. When board decisions can be predicted in advance due to known alliances, the board is no longer functioning as a truly deliberative body.

This article outlines practical steps boards can take to unwind existing voting blocs and prevent them from forming.

Leadership, leadership, leadership

It’s no coincidence that almost every exceptional board of directors has a strong independent chair or lead director. And this is by far the most important element to dissuade voting blocs in the boardroom. With a strong, influential, and ethical board chair at the helm, the board is far more likely to operate as a cohesive, independent body rather than a collection of factions advancing individual agendas. A capable chair sets the tone for open dialogue, ensures all voices are heard, and reinforces a culture of accountability and trust. In doing so, they not only neutralize the formation of voting blocs but also elevate the overall effectiveness and integrity of the board’s decision-making.

In addition, a respected board chair can adopt other mechanisms to encourage directors to think independently rather than operate as factions. These include:

Executive sessions of independent directors: Regular executive sessions —without management present—create space for candid, unfiltered discussion among independent directors. These sessions help surface concerns that might otherwise go unspoken and reduce the risk of informal alliances forming outside the boardroom. Over time, they reinforce the expectation that each director’s primary obligation is to the enterprise, not to management or a particular constituency.

Fiduciary duty education: Ongoing education around fiduciary duties—particularly the duties of care and loyalty—grounds directors in their individual legal and ethical responsibilities. When directors are reminded that their obligation runs to the company and all its stakeholders, it becomes harder to justify bloc-style decision-making. A strong chair can periodically reinforce these principles, especially in moments of tension or high-stakes decisions.

Diverse director backgrounds: A board composed of directors with varied professional experiences, industry perspectives, and cognitive approaches is less likely to fall into groupthink or factional behavior. Diversity of background naturally introduces a wider range of viewpoints, making it more difficult for any single bloc to dominate the conversation. The chair plays a key role in drawing out these differing perspectives and ensuring they are constructively integrated into deliberations.

Committee independence: Well-structured, independent committees—particularly audit, compensation, and governance—help ensure that key decisions are vetted objectively and without undue influence. By empowering committees with clear mandates and independent leadership, the board reduces the likelihood that decisions are pre-aligned by informal groups. Effective chairs coordinate across committees to maintain alignment while preserving independence in judgment.

Board evaluations: Regular board and individual director evaluations provide a structured mechanism to assess dynamics, including any signs of factionalism or disengagement. When done thoughtfully—often with third-party facilitation—these evaluations can surface behavioral patterns that undermine independence. A strong chair uses the findings to recalibrate board culture, reinforce expectations, and address issues before they become entrenched.

Strong board leadership also starts with thoughtful director preparation, including setting new board members up for success.

From factions to fiduciaries

Ultimately, voting blocs are not just a governance nuisance—they are a signal that the board has drifted from its core purpose. Boards are designed to be forums for rigorous, independent thinking, where diverse perspectives are tested, refined, and ultimately aligned in the best interests of the enterprise and its stakeholders. When outcomes are predetermined by alliances, that essential function breaks down.

The most effective boards are not those that always agree, but those that debate openly, challenge constructively, and decide independently. Unwinding voting blocs, therefore, is less about eliminating relationships and more about reinforcing a culture where independence, accountability, and intellectual honesty take precedence over loyalty or convenience. With the right leadership and deliberate governance practices, boards can move from predictability back to true deliberation—restoring both their credibility and their value.
