# Burnout peaks among high-performing mid-40s to early-50s leaders

**Claim (confidence: high · testable):** Contrary to expectations that burnout primarily affects overworked early-career employees or disengaged late-career employees, current organizational data reveals that the **most severe burnout is occurring among people in their mid-40s and early 50s**.

Crucially, these are *not* average performers — they are the organization's **most experienced, capable leaders**, slated to move into senior roles. Their disengagement results in a catastrophic loss of momentum and institutional knowledge exactly when the company relies on them most.

**Evidence & attribution:** anchored by an [[entity-unnamed-global-ceo|unnamed global CEO]] in [[quote-ceo-burnout-demographic]] ('It's not where we expected it…') and [[quote-ceo-losing-momentum]] ('We are losing momentum at exactly the point we need it most.'). The enrichment corroborates this via Gratton's own LinkedIn framing and the HBR landing page, which states that the *most experienced midcareer employees are burning out just as they enter their most critical stage*.

This is the surface symptom whose root cause is [[claim-systemic-cohort-burnout]], and whose demographic surprise is captured as [[contrarian-burnout-demographic]]. See also [[concept-pivotal-40s]].
