Brexit and the UK Labour Market – Publicpolicyevents

Quick answer: How has Brexit affected the UK labour market? Mainly by changing who can move to the UK to work, which feeds into employment, wages and vacancies. Isolating that effect from the pandemic and the wider economy is difficult, so no statistic settles it.

This guide sets out the channels, the indicators and the traps in attribution. It sits within the wider economic impact of Brexit topic, and the sector-level detail is in brexit labour shortages by industry.

How Brexit reaches the labour market

Brexit works on jobs and pay through a chain of stages rather than a single shock. Following the chain in order shows where the evidence is strongest and where it is thinnest.

Kitchen work is typical of the labour-intensive jobs where comparisons between more and less exposed employers are drawn.

Rules on movement change. Ending free movement replaced the earlier arrangements for EU citizens with the UK’s own immigration system. This is the most direct policy change affecting workers.
Labour supply shifts. New arrivals from the EU face different conditions from before, and some existing workers may leave or choose not to come. The effect is on the number and mix of people available to employers, not on demand for their work.
Employers adjust. Firms facing a smaller pool can raise pay, widen recruitment to other groups, train existing staff, invest in equipment, or reduce what they offer. Each response leaves a different mark in the data.
Trade and investment effects add to demand-side changes. Changes in trading conditions can alter how many workers firms want, separately from how many are available. This is why labour supply alone does not explain the aggregate picture.

The practical point is that supply and demand effects can offset or mask each other. A fall in available workers might push wages up, while weaker demand might push them down, so a flat aggregate figure can hide two real movements.

Packing and dispatch work of this kind is the sort of role where employers’ recruitment choices, and so labour supply, are most visible.

Reading the aggregate indicators

Three headline measures describe the labour market as a whole: employment, wages and vacancies. Each answers a different question, and each needs a different caution.

Employment and unemployment

Employment and unemployment rates show whether people who want work are finding it. They are slow to reflect a change in labour supply, because employers can often fill roles from other groups, and people who leave work may drop out of the unemployment count altogether. Employment levels on their own therefore say little about whether Brexit mattered. Participation, meaning how many people are working or looking, gives a fuller picture alongside them.

Public library computers are a common place to search for work, which is the activity unemployment statistics try to capture.

Wages

Wages show how scarce workers are relative to demand. If Brexit tightened supply in particular jobs, pay would be expected to rise faster there than elsewhere. Aggregate pay growth blends many forces, including inflation, minimum wage policy and bargaining, so a pay rise cannot be credited to Brexit without a comparison group.

Vacancies

Vacancies show how many roles employers are trying to fill. A high vacancy count alongside modest unemployment points to difficulty matching workers to jobs, which is the usual meaning of a labour shortage. Vacancy data records openings, not unmet need, and firms may advertise more widely when hiring is hard. A count that rises for any reason will therefore look similar in the headline series.

Separating Brexit from everything else

The central difficulty is the counterfactual: what the labour market would have looked like had the UK stayed in. Nobody observes that, so researchers approximate it. The strength of any claim depends on how convincing the approximation is.

Several developments overlapped with Brexit and moved the same indicators:

The pandemic. Lockdowns, furlough schemes and changes in who was working or looking for work disturbed employment, vacancies and migration at the same time as the new immigration rules took effect.
Population ageing and health. Changes in who is available to work affect participation regardless of the UK’s relationship with the EU.
The economic cycle and prices. Inflation, interest rates and energy costs shape both hiring and pay. Their influence on prices is covered in has brexit increased food prices uk, and the same caution applies to wages.
Other countries’ experience. Many economies faced tight labour markets after the pandemic. A UK-specific effect only shows up if the UK moved differently from comparable countries.

For this reason, the most credible analysis looks at differences: sectors or regions more reliant on EU workers compared with those less reliant, or the UK compared with similar economies. A difference that appears only where the policy bites is stronger evidence than any national average.

Where the evidence comes from

Different publishers answer different parts of the question, and they are best used together.

Hiring decisions, made one interview at a time, are where changes in labour supply turn into the pay and vacancy figures in national statistics.

ONS labour market statistics. The Labour Force Survey and the vacancy statistics supply the headline employment, pay and vacancy measures. Researchers can also reach survey microdata through the UK Data Service, which describes its holdings as the UK’s largest collection of economic, population and social research data.
Migration Advisory Committee reports. These assess how immigration rules relate to labour needs and are useful for understanding the policy side.
Home Office migration statistics. These record visas and entries, which show how the supply channel is changing.
Resolution Foundation and Institute for Fiscal Studies analysis. Independent research that tests attribution and compares groups, and often explains the trade-offs in plain terms.
Bank of England Agents’ reports. Summaries of what employers report about recruitment and pay, which add context the statistics lag behind.

What this means in practice

Treat Brexit as one important influence on labour supply and not as the sole explanation for national figures. Whoever reads a claim that Brexit caused a particular jobs or pay outcome should ask which comparison supports it.

Policy readers should look for analysis that compares exposed and less exposed groups, rather than relying on national totals.
Employers are better served by their own sector evidence than by aggregate figures, because recruitment difficulty varies sharply by role and place.
Job seekers gain most from reading vacancy and pay trends for their own occupation, since a national average can differ greatly from local conditions.

Where a source reports a clear effect, check whether it compares like with like and whether the pandemic period is handled separately. Where it reports only a national average, treat it as a description of the labour market and not as proof of cause.

Frequently asked questions

Did Brexit cause labour shortages?

It is one plausible cause, mainly through the change in rules on movement for EU workers. Other factors overlapped, so the share attributable to Brexit is a matter of estimation. Sector evidence is the better guide.

Which indicator best shows a Brexit effect?

No single indicator does. Wages and vacancies in occupations that relied on EU workers, compared with less exposed occupations, are more revealing than national employment totals.

Why is the effect hard to measure?

The comparison case, a UK that stayed in the EU, cannot be observed. The pandemic, inflation and demographic change also moved the same indicators at the same time.

Where can the underlying data be found?

ONS publishes the main labour market series, and the UK Data Service provides access to survey datasets for researchers. Home Office statistics cover migration, and think tanks publish analysis built on these sources.
