Workplaces are becoming more age-diverse than ever before, leaving organisations with a different kind of diversity challenge – how to ensure different generations collaborate effectively without friction.

Regular followers will know I debate these topics on an ongoing basis with Danielle Farage on our From X to Z podcast, but for today’s newsletter I’m looking at recent research published by the The British Psychological Society which looked at how age-related tensions develop – and more importantly – how they can be reduced through meaningful contact, inclusive culture, and thoughtful team design.

The Roots of Intergenerational Conflict

With up to five generations now sharing workplaces, it’s no surprise that tensions can arise between older and younger employees. The BPS study defined intergenerational conflict as disagreement, friction, or tension between employees of different age groups –  and links it to reduced team performance, wellbeing, and satisfaction.

But these conflicts aren’t simply about differences in work habits or communication styles. They’re rooted in social categorisation – the instinctive way humans group people into “us” and “them.” When workers feel that their age group is undervalued or discriminated against, this perception – known as Perceived Age Discrimination (PAD) – tends to heighten awareness of generational divides.

This usually results in defensiveness, stereotyping, and more frequent clashes – both about tasks (how work should be done) and relationships (how people relate day-to-day).

The researchers emphasised that both younger and older employees experience Perceived Age Discrimination – younger workers may feel dismissed as inexperienced, while older ones may feel sidelined or outdated. Either way, the sense of unfair treatment fuels tension.

When Work Structures Make Things Worse

Conflict doesn’t occur in isolation – it’s how work is structured that matters. The study found that task interdependence (the extent to which employees rely on one another to complete their work) can intensify conflict when Perceived Age Discrimination is present. In highly interdependent teams, employees have no choice but to collaborate closely. When age-based discrimination or mistrust already exists, this enforced co-operation can magnify frustration and disengagement.

However, interdependence isn’t the enemy – it can also become a powerful connector, provided the right conditions for collaboration are in place. The key lies in the quality of contact between colleagues.

The Power of Positive Contact

The BPS researchers highlight good quality, cross-age contact as one of the most effective ways to foster harmony. This means natural, voluntary, and respectful interactions between age groups – allowing people to learn more about each other as individuals, and not as stereotypes. Positive contact helps break down what’s known as “ingroup” and “outgroup” thinking, reducing perceived discrimination and strengthening trust.

Unsurprisingly (well, to me anyway!) the study found that when cross-age contact is high in quality, the benefits of task interdependence are amplified. Working closely together under these conditions doesn’t heighten conflict – it actually deepens mutual understanding and cooperation.

What Organisations Need to Do

The takeaway for HR and business leaders is clear: you can’t manage intergenerational dynamics through policy alone – you need to build connection. This means:

Creating structured opportunities for intergenerational collaboration that go beyond task assignments – for instance, mentoring partnerships, reverse mentoring, or cross-age project teams.

Training managers to spot signs of perceived age discrimination and address them through inclusive communication and recognition practices.

Celebrate age diversity as a strategic asset, not a challenge – blending experience with fresh perspectives creates stronger problem-solving and innovation.

The researchers concluded that the goal isn’t to minimise differences, but to turn them into a source of strength.

When employees of all ages feel respected and connected, organisations gain not only workplace harmony but also resilience and creativity – which are the hallmarks of a truly multigenerational workplace.
