Around 60% of senior-level women report frequent burnout, and among those newer to leadership, that number rises to 70% simply because of the conditions required to advance and sustain leadership roles.
For years, organizations have responded by investing in development — building skills, increasing confidence, and preparing women for leadership — operating under the assumption that advancement gaps are a function of readiness.
But the data suggests a different conclusion.
Women are not falling behind because they lack capability. They are falling behind because they are being developed in areas that do not drive promotion, while the factors that actually determine advancement — visibility, sponsorship, and access to decision-makers — are unevenly distributed.
I've seen this dynamic play out repeatedly inside organizations, particularly in environments where leadership development is taken seriously.
High-performing women are often the most invested in. They are given additional responsibilities, asked to mentor others, relied upon to stabilize teams, and consistently trusted to deliver results. Their managers view them as indispensable and frequently position them as key contributors to business outcomes.
But when promotion discussions take place — whether formally in succession planning sessions or informally in leadership conversations — the criteria shifts in ways that are rarely made explicit.
The discussion moves away from output and toward questions of visibility and perceived readiness: Who has been seen operating at the next level? Who has built relationships with senior stakeholders? Who has advocates willing to put their name forward in high-stakes conversations? In those moments, it becomes clear that performance alone is not the deciding factor.
Two Different Systems
What most professionals misunderstand is that development and advancement operate on two different systems.
Development is centered on performance. It focuses on building capability, strengthening execution, and improving outcomes within a current role. Advancement, however, is driven by perception and exposure — i.e., how an individual is viewed across the organization and who is actively advocating for their progression.
This is where the gap becomes structural.
Research consistently shows that employees with sponsors — those who actively advocate for their advancement — are promoted at nearly twice the rate of those without. Yet women are less likely to have sponsors at every level, meaning they are systematically underrepresented in the very conversations where promotion decisions are made.
What I've consistently seen across organizations is that women are over-developed in performance and under-positioned in exposure.
From the earliest stages of a career, women are more likely to be evaluated — and promoted — based on what they have already proven. Men, by contrast, are more often advanced based on perceived potential, which is inherently tied to visibility and confidence in future capability rather than past output.
At the same time, women are less likely to be recommended for the types of opportunities that signal readiness for advancement. Only 22% of women report being recommended for stretch assignments, compared to 32% of men. These assignments are not simply developmental — they are mechanisms for increasing visibility, expanding networks, and demonstrating leadership presence to decision-makers.
The implication is less about having a slower progression. It is a fundamentally different experience of the system, where women are required to demonstrate more while being given fewer opportunities to be seen at the level they are aiming to reach.
Mentorship Versus Sponsorship
This is where the distinction between mentorship and sponsorship becomes critical.
Most organizations have made meaningful investments in mentorship. Women are paired with leaders who provide guidance, feedback, and support, helping them navigate challenges and improve performance. While valuable, mentorship operates primarily within the development system, it helps individuals become better at their current role.
Sponsorship operates in the advancement system.
Sponsors use their influence to create opportunities, advocate in decision-making forums, and ensure that individuals are visible in the right contexts. Research reinforces that sponsorship is one of the most significant drivers of promotion, yet women are less likely to have access to sponsors, particularly at more senior levels where advancement decisions carry greater weight.
The Compounding Effect
Over time, these dynamics create a compounding effect.
Women continue to deliver, continue to grow, and continue to take on more responsibility. But without corresponding increases in visibility and advocacy, that effort does not translate into advancement at the same rate. The result is a growing disconnect between contribution and progression.
By the time women reach senior leadership, the cost of navigating this system becomes more visible. Burnout increases, pressure intensifies, and the expectations associated with leadership roles become more demanding. Data shows that a significant percentage of senior women experience sustained burnout, particularly those newer to leadership who are still working to establish credibility and stability at that level.
To put it directly, this is a reflection of the additional effort required to operate in a system where advancement inputs are unevenly distributed.
At a certain point, many high-performing women reach a decision threshold.
They begin to evaluate not just whether they can advance, but whether they want to, given what advancement actually requires. They see the level of visibility, advocacy, and sustained pressure necessary to succeed at higher levels, and they assess whether that path aligns with their long-term goals.
When organizations interpret this shift as a lack of ambition, they miss the underlying issue entirely.
This is not about ambition decreasing. It is about awareness increasing.
If the Goal Is to Advance, the Strategy Must Evolve
Continuing to focus exclusively on performance and development will not produce a different outcome. Advancement requires a deliberate shift toward positioning, ensuring that work is visible at the right levels, building relationships with leaders who have influence over promotion decisions, and communicating impact in ways that resonate beyond immediate teams.
Organizations that want to close this gap will not do so by continuing to invest solely in development.
They will do so by addressing how visibility, sponsorship, and access are distributed, and by aligning advancement processes with how decisions are actually made.
