LONGEVITY LEADERSHIP BRIEFING • MAPPING THE NEW Q3 • WEEK 3

Exploring how longer lives are reshaping work, careers and organisations.

If Sunday’s recent pieces map the scale of the demographic shift and its many loosenings, this Tuesday series asks a different question: what does that shift actually do to work? Because longer lives are not simply extending careers. They are restructuring them. The traditional life model—education, work, retirement—was built for shorter lives. What is now emerging is something more complex:

This new phase—Q3—is not a continuation of midlife work. It is a transition point. A period of reassessment, redesign, and, increasingly, reinvention. Yet most organisations are still operating as if nothing has changed - which shows how badly we misunderstand it.

Because while the over-50 population is growing rapidly, most organisations still treat it as a single, undifferentiated group—“senior talent”, “late career”, or simply “older workers”. In reality, Q3 is anything but uniform.

The next challenge isn’t just recognising Q3. It’s learning how to see the very different lives unfolding within it.
