For the first time in modern history, five distinct generations are working side by side.
Traditionalists. Baby Boomers. Gen X. Millennials. Gen Z.
All in the same teams, the same meetings, and the same Slack channels—bringing radically different expectations about everything from how feedback should be delivered to whether "work-life balance" is even a meaningful concept.
By 2030, Millennials and Gen Z alone will make up roughly 74% of the global workforce.
But older workers aren't disappearing; they are staying longer, with over-65s projected to account for nearly 9% of the labour force by 2032.
The window for treating generational diversity as a "soft" issue is closing fast.
Your managers are caught in the middle of this shift.
And most of them have no idea how to navigate it.
Research from the London School of Economics (LSE) paints a stark picture. In a study of 1,450 employees, the LSE found that friction between generations is actively dragging down productivity.
The numbers are striking. 37% of Gen Z workers report low productivity levels, compared to just 14% of Baby Boomers.
But here is the kicker: employees with managers more than 12 years their senior are nearly 1.5 times as likely to report low productivity.
This isn't about lazy young people or out-of-touch older workers.
It's about a fundamental failure to bridge communication gaps.
According to the Society for Human Resource Management (SHRM), 67% of companies report experiencing intergenerational conflict.
Furthermore, Deloitte found that 60% of workers believe their organisation doesn't communicate effectively across age groups.
The question isn't whether generational differences are affecting your teams.
They are.
The question is whether your managers have the skills to do something about it.
Before we go further, let's be clear about who we're talking about and what shaped them.
Research consistently shows that conflict doesn't come from "values" as much as it comes from mechanics.
Communication Styles
51% of Baby Boomers report little to no interaction with younger generations. When they do interact, the medium matters. Boomers often prefer phone calls. Gen Z defaults to instant messaging. Without ground rules, this leads to frustration on both sides.
Feedback Expectations
This is a major flashpoint. Boomers typically assume "no news is good news." Millennials and Gen Z expect constant input. A Boomer manager who provides annual reviews may believe they are doing their job, while their Gen Z direct report feels invisible.
Work-Life Boundaries
For Boomers, long hours often signalled dedication. Gen Z takes a different view: 59% say they would quit if their manager didn't take their career planning seriously, but they also expect that career to fit around a life, not consume it.
Here's where managers often go wrong: they read an article like this, create mental shortcuts, and start treating all Boomers one way and all Gen Z another.
As one expert put it:
"You do not want to end up with cheat sheets for communicating with Baby Boomers.
Imagine if someone said they have a cheat sheet for communicating with people in any other diversity category."
Generational tendencies are real, but individual variation is enormous.
The danger of stereotyping is that it creates exactly the kind of resentment that fuels conflict.
The managers who successfully lead multigenerational teams share common approaches.
Here's the uncomfortable truth: most managers have never been trained to handle any of this.
Data from the Chartered Management Institute (CMI) reveals that 82% of managers enter their roles without formal training.
They are expected to navigate complex team dynamics through instinct.
That might have been adequate when workforces were more homogeneous.
It's not adequate now.
The LSE research is blunt: "The skills that are required to manage these dynamics are not usually being taught by firms. Our research shows that if we invest in giving these skills to managers... there are significant productivity gains to be had."
Organisations that effectively manage generational diversity don't just avoid problems—they gain advantages.
Deloitte's research found that diverse and inclusive teams outperform others by approximately 35%.
Similarly, Gallup reports that teams with engagement across generations are 21% more profitable.
But these benefits don't materialise automatically.
They require skilled managers who can harness diversity rather than being derailed by it.
If you're a manager reading this, here's the bottom line.
Your team members from different generations aren't difficult.
They're different.
And "different" only becomes "difficult" when you expect everyone to work exactly like you do.
Your job isn't to change their preferences.
It's to understand them, work with them, and help your team collaborate effectively.
That requires skills. And skills can be developed.
Our management training programmes help managers develop the interpersonal capabilities needed to lead diverse teams effectively.
From communication and influencing skills to having difficult conversations, we focus on the practical abilities that make the difference.
