An article recently published in Les Echos — the French economic newspaper of record — commented on a new survey about age discrimination at work. According to Eurostat, the average working life spans 36 years. Yet many companies still believe the “golden age” for career acceleration is between 30 and 45. Is that really it? A 15-year window — and then… what? No hope?

Fifteen years sounds like a lot. Until you compare it to the 40+ year arc of your working life. Then it feels cruelly short

More than two-thirds of the 1,300 men and women surveyed by Ipsos BVA between April and June 2025 for the association Grandes écoles au féminin (GEF) agree. And 68% say their age has already held them back at work.
And it’s not just older professionals. Younger ones are trapped too.
You studied for years. You broke into the job market — sometimes with grit, sometimes with luck. You climbed, slowly, painfully, with sweat and sleepless nights. Now you’re in your 30s — finally out of the woods, finally “in.” And now? This is your window. The one that will slam shut before you know it.

Oh — and if you’re a woman? It gets worse

Because 30–45 is also when many of us choose to start families. To have children. And let’s be honest: maternity leave and early childcare? Not exactly career accelerators.
So here you are — double-layered pressure. “Make it or break it” before your kids even hit high school.
Now, from the other side of the window — late 40s — does it get better?
You’ve earned credentials. You’ve mastered competencies. You’ve stayed current — no, you’re not behind on tech. Thank you for asking.
Does that experience bring comfort? It should. But here’s the cruel paradox: the more capable, the more eager to learn, the more ready to share your magic with your team — the more you hit the invisible wall. It has a name: seniority bias.
Let’s be real: with retirement ages rising globally, we’ll all be working into our 60s. That’s not a bug — it’s a feature. We’re living longer, healthier lives. So why are we still clinging to century-old clichés that people over 50 are “less productive”?
And let’s not pretend this hits everyone the same.
Women — of all ages — get the double whammy.
When you’re young? You hear it. “Too young.” “Not seasoned enough.” “Still figuring things out.” Comments that never seem to land on your male peers.
When you’re older? The invisible wall thickens. Promotions stall. Pay raises vanish. Recognition fades — while your male counterparts? They keep climbing. Quietly. Steadily. Unbothered.
It’s not a coincidence. It’s biased. Layered. Gendered. Ageist. And it’s costing companies talent — and costing women their rightful place at the table.

The only thing that matters? How you act

I could rant about this double-bind for days — the no-win trap where professionals face precarity for no reason, and companies starve themselves of seasoned, high-value talent — all because of outdated prejudices.
Knowledge is power. So don’t look away. Don’t pretend it doesn’t exist.
You don’t have to let ageism undermine you. You have to outsmart it.
Define your strategy. Own your value. Go get what’s yours — a fulfilling, impactful career — no matter where you are in your journey.
