Picture two people in the same company. One is a 58-year-old who knows every supplier quirk and client history, and who is slowly being nudged towards the exit. The other is a 29-year-old with real leadership potential, waiting for a chance that never comes because nobody will talk about who is moving on. Both situations cost the business something. Tackling ageism in the workplace takes more than a diversity statement. Leaders have to look honestly at how age shapes hiring, development, performance reviews and the question of who gets to lead.
The topic is back in the spotlight after Christina Wing’s Harvard Business Review article, Leaders Must Speak Honestly About Aging at Work (October 20, 2026). Her argument is that dodging candid conversations about retirement and succession harms organisations, stalls emerging leaders and leaves experienced executives unprepared for what comes next.
The starting point for leaders is simple. Age doesn’t tell you how ambitious, adaptable or ready to retire someone is. An age-inclusive workforce gives people at every career stage room to contribute, learn and plan ahead, without anyone guessing what a person of a certain age “should” want.
What is Ageism in the Workplace?
Ageism in the workplace means stereotyping, disadvantaging or treating someone unfairly because of their age. It cuts both ways. Older professionals get written off as too experienced, too expensive or too set in their ways. Younger employees get dismissed as green, however good their judgement.
It rarely shows up as an openly offensive remark. More often it’s a quiet assumption inside an ordinary decision: that a veteran will struggle with new software, or that a younger manager can’t handle a tricky client.
Here is where it tends to appear:
- Recruitment: A qualified candidate is passed over because the manager wants someone younger, or assumes an older applicant “won’t fit the culture.”
- Training: Digital skills courses and high-profile assignments go mostly to younger staff.
- Promotion: Age is used as a stand-in for potential, so experienced people get overlooked or younger people are judged not ready.
- Performance management: An older employee’s working style is read as resistance to change, without anyone checking the actual results.
- Retirement: Someone is pressured to leave because of their age, rather than being asked about their plans and preferences.
On the legal side, the US Age Discrimination in Employment Act generally protects workers aged 40 and over in covered employment. Rules differ by country, so organisations with international teams need to know what applies where. But age discrimination at work is a management problem as well as a legal one. Decisions should rest on skills, performance and business needs, not on stereotypes.
Why Age-Inclusive Leadership Matters
It’s easy to file this under HR. In practice it affects how well a company grows talent, passes on knowledge and handles leadership changes.
The US Equal Employment Opportunity Commission’s 2018 report on age discrimination showed how outdated assumptions about older workers stop organisations from using their experience. It also reviewed evidence linking age-diverse teams to better engagement, performance and productivity.
Four things deserve a leader’s attention.
- Talent retention and institutional knowledge. Experienced people often carry things no document captures: why a decision was made, which supplier needs careful handling, where the operational risks hide. When they’re overlooked or leave without a handover, that context goes with them.
- Leadership succession. Succession planning stalls when nobody will mention future transitions. If a senior leader’s eventual departure is never discussed, the people who could replace them don’t get enough time to build the judgement and relationships the role demands.
- Skills development. Assuming older employees don’t want to learn closes doors for them. Assuming younger ones are naturally fluent in every new tool leaves their real gaps unnoticed.
- Collaboration across career stages. People at different stages bring different experience, networks and angles on a problem. Age-diverse teams can turn that into better decisions, as long as managers make it safe to contribute and to disagree respectfully.
None of this is about protecting one generation at another’s expense. It’s about making talent decisions based on what each person can actually do and what the organisation actually needs.
How Leaders Can Build an Age-Inclusive Workforce
A statement supporting diversity won’t achieve much if everyday decisions keep rewarding one age group. The real work is in the systems that decide who gets hired, trained, promoted and trusted.
- Judge performance on evidence, not assumptions
Assess people against clear role requirements, agreed goals and results you can observe. Don’t use age as a shortcut for energy, technical skill or appetite for learning.
Say a manager suspects a seasoned colleague is struggling with a new system. The fair response is to check their actual proficiency and offer support where it’s needed. A younger employee in the same position should get the same treatment.
A few habits help:
- Use consistent criteria for comparable roles.
- Ask managers to back promotion and development decisions with evidence.
- Check whether people of different ages get similar access to training and stretch assignments.
- Look for patterns in hiring, pay, ratings and promotions that might point to bias.
The goal is decisions you can defend, not a verdict on what any age group can or can’t do.
- Keep succession planning going all year
Succession planning is usually tied to a looming retirement or a CEO’s departure. By then there’s often little time left to prepare anyone or capture what the outgoing person knows.
Wing’s HBR piece highlights what avoidance costs. Leaders can act on that by separating succession planning from guesses about when someone will leave. In practice that means:
- Identifying roles where losing specialist knowledge would create real operational risk.
- Developing more than one possible successor for critical positions.
- Talking about career goals well before a transition becomes urgent.
- Letting potential successors lead projects, manage budgets and build stakeholder relationships.
- Writing down essential processes and decisions so knowledge doesn’t sit with one person.
These conversations should be about continuity and individual preferences. They shouldn’t become a polite way of pushing older employees out the door.
- Open learning and development to everyone
Development shouldn’t stop at a certain age, and it shouldn’t be withheld from someone seen as too young to need it. Organisations can make it fairer by:
- Basing digital, technical and leadership training on the role and the person’s goals.
- Making internal vacancies and stretch assignments visible across all age groups.
- Holding career conversations that ask about ambitions, not assuming senior people want to coast.
- Assessing skills directly when new technology or responsibilities arrive.
- Supporting moves into specialist, advisory, mentoring or management roles that suit the individual and the business.
It’s also worth checking who actually shows up to training. If one group keeps getting fewer opportunities, look at eligibility rules, manager recommendations and assumptions about how long someone will stay.
- Share knowledge in both directions
Mentoring can preserve expertise, but it goes wrong when it assumes older people always have wisdom to give and younger people always need guidance.
Treat it as a two-way exchange. A veteran engineer might explain why a production process was built the way it was, while a newer colleague introduces a faster analytical tool. Both come away knowing more. Some formats that work:
- Reverse mentoring: Pair people so each shares expertise in their own area.
- Cross-generational project teams: Give people of different ages shared ownership of a real business problem.
- Structured handovers: Record key decisions, procedures, customer context and lessons from past projects.
- Peer learning: Let colleagues teach each other without age being the main sign of who’s the expert.
The point is to make knowledge available across the organisation instead of tying it to particular people or generations.
- Make age something you can talk about
Managers often steer clear of the subject because they’re afraid of saying the wrong thing. The trouble is that silence lets stereotypes drive decisions unchallenged.
Some ground rules help:
- Ask people what they want rather than inferring it from their age.
- Raise performance concerns with specific evidence.
- Let employees explain their own ambitions and circumstances.
- Drop jokes and labels that suggest someone is too old to learn or too young to lead.
- Keep retirement discussions respectful and appropriate, within the law and the person’s employment terms.
So, a manager might ask, “Which skills do you want to build over the next few years?” instead of quietly assuming someone is winding down. And a younger employee’s readiness to lead should be judged on evidence, not waved away as inexperience.
These conversations should feel like a normal part of managing people, not something triggered by a birthday.
How Can You Tell If It’s Working?
Good intentions are hard to evaluate without data. Look at whether people of all ages have comparable access to opportunities and whether your policies treat them fairly across a whole career.
| What to track | What it can show |
| Hiring outcomes | Whether qualified candidates face different barriers at different ages |
| Training participation | Whether access to new skills is equitable |
| Promotion and internal mobility | Whether progression depends on demonstrated capability |
| Retention and exit patterns | Whether some groups leave under different circumstances |
| Succession readiness | Whether critical roles have prepared successors and documented knowledge |
| Employee feedback | Whether people feel respected and able to discuss their plans |
Read these numbers with care. A gap between age groups doesn’t prove discrimination, since role requirements or workforce make-up may explain it. What matters is spotting patterns, finding the cause and fixing what’s unfair. Protect employee privacy too, and never use age data to label individuals or predict what they want.
Retirement, Succession and Career Growth Aren’t the Same Decision
One of the harder parts of managing an age-diverse workforce is accepting that these three things are linked but separate.
A company can prepare for a leadership handover without assuming its current leader is about to retire. One experienced employee may want to keep going as before. Another may want a different role or lighter responsibilities. Another may be ready for a new chapter. You can’t know which without asking.
The sensible path is to plan for continuity while respecting individual choice. That lets you prepare successors, spread critical knowledge and open up advancement without turning age into a countdown to departure. It also means accepting that growth doesn’t have to stop at a particular age, and that readiness to lead doesn’t arrive on a particular birthday.
Conclusion
Left unchecked, ageism in the workplace erodes talent retention, succession planning and employee development. Asking people to respect each other isn’t enough. Organisations have to look at the systems that hand out opportunity, responsibility and recognition.
The best leaders pair fair performance standards with open career conversations, steady learning and deliberate knowledge transfer. They plan for succession without presuming when anyone should leave, and they give emerging leaders room to grow without undervaluing the people whose experience keeps the place running.
An age-inclusive workforce doesn’t need everyone on the same career path. It needs a workplace where people can contribute, develop and prepare for change based on their abilities and goals.
The real test is whether an organisation can plan for its future without making assumptions about the people who will build it.
Author’s Note
I have often noticed how easily people make assumptions about what someone can or cannot do at a particular stage of life. An experienced professional may be overlooked when new opportunities arise, while a younger employee may have to work harder to prove that they are ready to take on responsibility.
Watching these situations unfold has made me realise that age can influence workplace decisions, even when an organisation believes it treats everyone fairly. For me, age-inclusive leadership begins with listening before making assumptions, recognising ability beyond years of experience, and giving people the space to decide what growth means to them. A person’s age should never become a limit that someone else places on their potential.
