The “Gut Feeling” vs The Data

Let’s start with the social contract we’ve all quietly agreed to in this country: you do not talk about money, not at the office, not at the dinner table, and absolutely not with the colleague sitting two desks away from you. It is treated as something between bad manners and outright aggression. As if asking whether your salary is fair is the same as announcing that you are greedy, ungrateful, or both. So, how do employees know if they are underpaid?

The silence that we talked about doesn’t protect you. It protects the status quo. And there is a real internal conflict here that a lot of people feel but never say out loud. You might genuinely like your job. You might like your team, your manager, the commute, and the flexibility. You don’t want to come across as difficult or demanding. So you push the thought away and tell yourself you’re probably fine. But liking your job and being paid fairly for it are two separate things, and one does not cancel out the other. You are allowed to want both.

Here is the harder truth: industries shift fast. Salaries tend not to follow. A package negotiated three years ago reflected what the market looked like three years ago, before inflation, before your skills grew, before your role quietly became something bigger than the job description you originally signed. Your gut reeling that something is off might be right. The five checks below will tell you whether it is.

#1: Your Responsibilities Have “Grown” (But Your Pay Hasn’t)

Think about the week you started your current job. There was a role. A scope. A set of things you were hired to do, with a job title that matched. Now think about last week. Were those the same things?

For many people, the honest answer is no. A colleague left, and their tasks were quietly redistributed without fanfare. A new project came in, and you were the obvious person to run it. A system changed, and somehow you became the go-to person for managing it, on top of everything else. None of it came with a conversation about pay. It was framed as growth, an opportunity, or just the way things go. And you got on with it, because that’s what you do. The problem is that a job title that no longer matches the actual scope of your work is one of the clearest early signs your current salary has already started to fall behind.

Many ambitious workers want the extra responsibility. For them, it feels like personal growth, progression, a movement in the right direction. And we don’t negate this. But personal growth and fair compensation must go hand in hand. When one happens without the other, the gap quietly widens, and by the time it feels significant enough to raise, you have often been absorbing extra work for a year or more without a penny of recognition for it.

The Check: Compare your current daily tasks to your initial job description

#2: The “Market Mirror” Doesn’t Match

Your current salary is also shaped by what the market is paying for your skills at your level and in your sector right now. And the good news is that salary data is more accessible than ever. For example, Olive Recruit’s latest Salary Guide gives you a role-by-role breakdown across 10 UK regions and 105 job roles. It is a practical starting point for grounding your salary negotiation in real numbers rather than assumptions.

What’s more, job postings on Reed, Totaljobs and LinkedIn are displaying salary ranges far more often than they used to. Glassdoor carries self-reported salary data across thousands of roles. Recruiters publish benchmarking guides. Multiple sources can provide you with the “Market Mirror” and match your data to your specific sector. But you must approach the data honestly, rather than selecting the most optimistic figures. A fair comparison looks at roles with comparable job titles, experience levels, and regions. If your current salary is in the bottom 25th percentile despite having real mid-career experience, you should prepare for a proper salary negotiation.

Industry standards shift faster than most pay reviews do. What counted as a competitive package for your job title three years ago may now sit below what the same role attracts at the average employer. This is especially true in sectors that have seen rapid growth in demand. Healthcare professionals, for example, have seen significant movement in market rates over the past few years as NHS pressures and private sector competition have pulled salaries in different directions. The same pattern plays out across tech, social care, finance, and operations. Whatever your sector, checking your current salary against live market data, such as comparing job listings for similar roles, must remain high on your priorities list. Losing it from your sight for just a month or two could mean losing paycheques in the long run.

The Check: Is your salary in the bottom 25th percentile for your role despite having mid-level experience?

#3: You’ve Stayed Put While the Market Moved

There is an uncomfortable pattern that plays out in workplaces across the UK. Companies offer their best salaries to people they are trying to attract. The people already sitting in the building, who have been there for years and know everything about how the place runs, tend to get smaller increments at annual reviews, if they get anything at all.

The new hire joining the same team next month might be offered more than you earn now for doing the same job. You should know that this is not deliberate. It is just how pay structures drift when they are managed reactively rather than proactively. People who move jobs every few years tend to outpace people who stay, even when the stayers are the strongest performers. This process is therefore also known as “Loyalty Tax”.

On top of that, inflation turns this process into a compounding issue of chasing stagnation. A 3% pay rise sounds reasonable in isolation. But add the cost of living, where it rises by 6-7%, and what you get is actually a pay cut instead. Over the years, the effect adds up quietly, even though you are earning more than you were in the beginning.

The Check: When was your last salary review, and did it exceed the current inflation rate?

#4: Recruiters are “Cold Calling” with Higher Numbers

If you have been in your field for a few years, you have probably had a message or two drop into your LinkedIn inbox from a recruiter about a role you weren’t looking for. Most people delete them and move on. But if those messages are becoming more regular, and the numbers being mentioned are consistently higher than what you currently earn, that pattern is worth paying attention to.

Recruitersdon’t message at random. They search for people with specific skills in specific sectors, match them against the actual market offer, and reach out when they think there is a fit. When a recruiter tells you that a similar role to yours is being advertised at £5,000 or £7,000 more than you currently earn, that is a sign that it’s time to renegotiate your salary. And also, an invitation to do a short, no-commitment conversation with the recruiter as a research tool to find out what your profile is worth at that given moment.

The Check: Use “market temperature checks” even if you aren’t actively looking to leave.

#5: High Turnover and “Quiet Hiring”

When people repeatedly leave a team, the reasons they give are usually vague.

  • New opportunity.
  • Personal circumstances.
  • Ready for a bigger challenge.

And sometimes they are true. But when the same team loses person after person over the course of a year or two, pay is almost always part of the picture. It is one of the most consistent factors behind voluntary resignations in the UK, and also one of the least likely to be stated openly in an exit interview, because people don’t want to diminish their relationships with their former company.

The “Quiet Hiring” factor is taking centre stage. It starts when a colleague leaves, and their work lands quietly on your plate, without a restructure, without a title change, without a pay adjustment. What it basically means is the companyhas effectively hired you to do two jobs for the price of one. It happens gradually, in the same way as all the other creeping changes on this list. A task here, a project there. Before long, you are taking on considerably more than you were paid to do, and no one has raised the higher salary that should follow.

The Check: Is the “replacement cost” for your role significantly higher than what you are currently being paid?

The “What’s Next?” Action Plan

Knowing that you’re underpaid and doing something about it are two different things. Here is a straightforward four-step guide to help you achieve a salary that aligns with your position and duties.

Step 1: The Research Phase

Before you speak with anyone, build your file. Write down your wins over the past 12 months, projects delivered, problems solved, targets hit, and responsibilities added. At the same time, gather the salary data:

  • job listings,
  • recruiter conversations,
  • salary guides.

This way, you will build a more specific and evidence-based case, which is a foundation of a productive salary negotiation process. Don’t forget, Olive Recruit is here to help you every step of the way. Check out our latest Salary Guide here.

Step 2: The Soft Approach

Do not request an urgent “Salary demand” meeting with your manager. That way, you could only put the other person in a defensive mode, even before the conversation starts. Instead, use your regular check-ins or schedule a one-on-one with your manager. Use these meetings focused on your achievements, career alignment, and milestones reached to discuss this issue further. So, here the salary talk could fit in completely natural. It leaves room for genuine dialogue rather than a tense yes/no situation.

Step 3: Preparing the Script

Let the previously researched pay ranges lead the way, because the most effective conversations are built around value delivered, not personal expenses and circumstances. Consider choosing: “I’ve taken on considerably more since my last review, and the market data I’ve gathered for our location and industry suggests my salary doesn’t currently reflect that” over “My mortgage has gone up.” Managers respond to business logic, and not empathy. Show them you’re worth it by showcasing 2 or 3 concrete examples of the impact you have had. This way, the specific salary figure would have a tangible, reasonable basis to stick to, and you could request your deserved pay rise with more confidence.

Step 4: Looking Outward

We must acknowledge that sometimes, the gap is too large to bridge internally. Pay structures in some companies are rigid. Budgets have real ceilings. And some companies, even ones with genuinely good intentions, cannot match what the market is paying right now. If you have had the conversation, made the case clearly, and the response has been either a flat refusal or a gesture that does not come close to reflecting the reality, it may be time to look outward. You have already done your research well, so it would be easier for you to reach out to a recruiter who can provide suitable career advice and determine your future career move together.

Being “underpaid” is a Temporary State, not a Permanent Reflection of Your Worth

Gone are the times when salaries were fixed, and markets moved extremely slowly. Now, many factors decide the value of your paycheque, and a lot of them actually depend on your qualities. If you have something to show on your side, be assured that someone on the other side will understand your worth and pay you adequately.
