Reward Heads
Using our heads to solve your Reward challenges.
Why are so many organisations struggling with pay fairness, even when their pay levels are competitive?
Why does a seemingly small gap, £1,000 here, £2,500 there, trigger frustration, disengagement or even resignations? And why does "transparency" sometimes make things worse rather than better?
These are the questions Reward teams are wrestling with every day. And the uncomfortable truth is this: the number itself is rarely the problem. The story behind the number is.
Across multiple studies, one pattern is unmistakable:
Employees don't just care what they earn — they care how what they earn compares to others, and whether the differences feel fair, consistent and explainable.
When people understand why someone earns more, and how they can get there too, pay differences feel like progression.
When they don't, even small gaps feel like injustice.
This is where organisations often fall down. They publish pay bands, share salary data, or talk about transparency — but without the explanation, structure and governance that make transparency meaningful.
And if that is missing, transparency becomes noise, not clarity.
It's not the number - it's the narrative
Imagine discovering your colleague earns £1,000 more than you. The discomfort you feel has very little to do with the £1,000. It has everything to do with whether the gap makes sense.
If you can say "That makes sense because…" they have more experience, a broader remit, a market-scarce skillset then the difference lands as logical.
But if your internal script is "That's not fair because…" we do the same job, no one has ever explained the difference, it feels arbitrary then the same £1,000 is seen as unfair
The actual pay difference is the same, it's the story that changes behaviour.
What the research tells us (and why it matters)
When the University of California made salaries searchable online, researchers studied what happened when employees were nudged to look up their colleagues' pay.
The results were striking; those earning below the median became less satisfied and more likely to look elsewhere. But those above the median didn't become happier. Being "ahead" doesn't give you a boost, but being "behind" definitely hurts.
A follow-on study sharpened the picture, finding out your manager earns more than you thought can be motivating as it signals progression and aspiration. However, finding out your peer earns more than you thought is usually demotivating, unless the difference is clearly explained.
The pattern suggests that Vertical differences feel like development space, but horizontal differences feel like an injustice, and this is the heart of the issue: employees judge fairness not by absolute pay, but by relative position and the clarity of the system behind it.
The noise of transparency without explanation: the Norway lesson
Norway has long made tax records public. But when those records moved online, and were suddenly accessible with a few clicks, something unexpected happened. The happiness gap between higher- and lower-income people widened, transparency didn't make things feel fairer. It made differences more visible and more painful.
This is the risk with "raw transparency":
More numbers do not equal more understanding, in fact, they often amplify frustration.
So, what actually works? A clear, consistent pay policy - and sticking to it
Across all the research, the conclusion is the same. you cannot manage perceptions of fairness with secrecy, as people will compare anyway, internally, externally, on job boards or in WhatsApp groups.
The real question is will they have a clear framework for understanding what they see? This is where pay policy becomes your strongest defense.
A well-designed, well-communicated pay policy should answer:
And just as importantly, does the organisation actually follow their own policy?
If the policy says one thing but real decisions say another, and there are unstructured out-of-cycle increases, deals for squeaky wheels, off-grid salaries then employees will believe what they actually see happening, not the policy, and that's when a £1,000 gap becomes toxic.
Victoria Milford, our CEO, has been making this point for years:
The issue isn't that someone earns more — it's whether the organisation can clearly explain why, and what it would take for others to get there too.
What this means for Reward teams
For Reward professionals, this evidence is actually empowering. It strengthens the case for:
This is exactly what organisations are asking us for at Reward Heads, frameworks that make sense, policies that explain them clearly, and governance that ensures they're lived in practice, and not just written on paper.
If this sounds familiar, we can help
At Reward Heads, we work with organisations to build pay frameworks that are commercially grounded, culturally aligned and practically manageable.
If you'd like to explore how we can support your organisation — whether that's job architecture, pay policy, governance or communication — reach out to the team at rewardsolutions@rewardheads.co.uk
We'd be happy to set up time to talk.
