The Chief Human Resources Officer has become one of the most strategically critical roles in business. Yet, at precisely the moment when organizational transformation demands continuity and vision at the top of the HR function, CHRO tenure is declining faster than that of any other C-suite role. According to new research from The Josh Bersin Company, average tenure has dropped by 20% — from six years to just 4.8 years — over the past decade. At a time when organizations need more leadership stability, they are getting less.

Why CHRO Turnover Is Rising

1. Expectations for the job have risen faster than CHROs can keep up. As the CHRO job grows more complex and critical to the business, CEOs and boards keep raising the bar for the type of leader they want. Expectations for AI transformation leadership, M&A know-how, cross-functional expertise, and board experience contribute to the perception that incumbent CHROs are falling short and need to be replaced.

2. Lack of awareness of the conflicting demands on CHROs. CEOs and Boards often lack awareness of the competing, relentless priorities facing CHROs. At any given time, CHROs are balancing the interests of their Board members, CEO, C-suite peers, HR team, and the workforce, while having to stay ahead of constantly changing employment laws and compliance requirements. Many CHROs report that they are barely treading water, feeling as though they are no longer building something, but instead reacting to one crisis and demand after another.

3. CHROs operate with less authority and pay parity than their C-suite peers. CHROs say that "influencing without authority" is one of the most difficult aspects of their job. Despite the expanded scope of the role, they report having to work harder than other executives to secure buy-in for strategies, transformation initiatives, and investments. They also experience a persistent compensation gap that other C-suite roles do not face to the same degree.

4. CHRO Burnout. Burnout among HR executives is at a critical inflection point, driven by an accumulation of crisis-level responsibilities that began with the global pandemic and now include artificial intelligence, which threatens to reshape not only the workforce but the very nature of work. Few executive roles have faced such a sustained period of complex people, business, and regulatory challenges. CHROs have become the organization's emotional shock absorbers, and many are deciding the role is simply not worth the cost.

5. A structural dependency on external CHROs creates a self-reinforcing cycle. Less than 20% of organizations promote their CHRO from within, compared to significantly higher internal promotion rates for roles such as CFO and COO. Without strong internal succession pipelines, CEOs must depend on hiring externally. This perpetuates the frequent rotation of existing CHROs among companies, without creating new candidates. More than 75% of CHRO appointments are now filled from outside the organization.

The Business Costs of CHRO Turnover

Organizations are perpetually starting over at the top of HR leadership, and that has significant consequences for the business.

Companies are investing in people strategy, culture transformation, workforce reskilling, and AI adoption. CEOs are also pushing for productivity, forcing redesigns of operating models, flattening hierarchies, and simplifying job architecture. The CHRO is the architect of continuity across all of these agendas. The loss of that leader mid-journey, without an internal successor in place, carries direct and measurable costs.

Every CHRO departure also takes years of institutional knowledge with it — knowledge about litigation, culture, leadership dynamics, and historical decisions that cannot be replaced.

CHROs are active C-suite members, but also confidantes to the CEO on high-impact and sensitive people initiatives such as executive succession, culture stewardship, and management behavior. The CEO and CHRO share a uniquely strategic, deeply interconnected partnership at the heart of organizational leadership, which is severed when a CHRO leaves. Replacing that partnership is disruptive to both the CEO and the broader business.

The Urgent Case for CHRO Development & Succession Planning

CHRO stability requires a dedicated focus on the development, equity, and succession of the person in the role. Here are the three most consequential actions organizations can take to reverse the trend and reduce the costs of CHRO turnover.

• Invest in CHRO development and support. CEOs must engage in deliberate, ongoing development of their executives to ensure resilient leadership continuity at the top. Pairing CHROs with external coaches who have held the role, providing rotational assignments in other functions to build business fluency, and involving them in enterprise-wide initiatives such as M&A, digital transformation, or business model innovation will ensure their capabilities and resilience keep pace with the business.

• Treat CHRO succession as a CEO and board imperative. To limit the disruption to the business and reliance on external hires, developing HR leadership capabilities from within should be a strategic business imperative. Organizations should identify high-potential HR leaders three to five years before a transition is likely and invest in structured development plans that include executive coaching, cross-functional assignments, board interaction, and enterprise leadership experience. Building a pipeline of capable internal HR candidates should be a mandate of the CEO, and boards should require a documented CHRO succession plan, just as they do for the CEO.

• Align compensation and authority with role scope. CHRO retention and succession planning will only work if the role is attractive enough to keep high performers. This means aligning CHRO compensation, reporting lines, and formal authority with other C-suite roles. Organizations that treat the CHRO as a peer to the CFO, CIO, and CMO — and compensate accordingly — will be better positioned to develop and retain talent at every level of the HR leadership pipeline.

Stop Starting Over

The CHRO role has never been more important — or more unstable. Average tenure is declining, external hiring dependency remains structurally entrenched, and the absence of robust internal succession programs perpetuates the revolving door. The business cost is not abstract: every CHRO departure is a setback that compounds over time, eroding organizational advancement and cultural coherence.

Companies that invest in CHRO development and succession planning — by building internal pipelines, rotating HR leaders through business functions, and pairing them with external coaches — will create stronger, more resilient executives at the top. Those that do not will continue to absorb the cost, disruption, and lost momentum that come with repeated exits, while forfeiting the compounding returns of leadership continuity.

The CEO's most important talent decision is not simply choosing the right CHRO. It is creating the conditions in which great CHROs are developed, supported, and ultimately succeeded.
