“The British economy is going part-time” makes a punchy headline. It also does what punchy headlines often do: squeeze a messy reality into a single villain.
Yes, the UK labour market is shifting in ways that look like less full-time work and more flexibility. And yes, the tax system is quietly making extra effort feel less rewarding for a growing number of workers.
But blaming this shift mainly on “Labour’s higher taxes” is a leap. The data support parts of the claim and undermine others.
What the labour market data actually shows
At a high level, the UK still has far more people in full-time work than part-time work.
- Full-time workers (Aug to Oct 2025): 25.58 million
- Part-time workers (Aug to Oct 2025): 8.64 million
That is not an economy abandoning full-time work. It is a large, stable part-time segment sitting alongside a much larger full-time workforce.
What has softened is the overall labour market momentum and working patterns.
- Average weekly hours worked have fallen over the past year, even though there was a small rise in the most recent quarter.
- Interest in compressed weeks, hybrid roles, and flexibility-first jobs has increased.
So the “part-time economy” story is better described as hours and preferences becoming more variable, not Britain collectively downshifting into part-time employment.
The tax piece: not always higher rates, but often higher take
This is where the claim starts to touch something real.
Labour pledged not to raise the headline rates of Income Tax, National Insurance, or VAT. On paper, that is true.
But governments do not need to raise rates to raise the tax burden.
They can freeze thresholds.
This process, known as fiscal drag, pulls more people into higher tax bands over time as wages rise with inflation.
Key facts and data points
- Headline tax rates have not increased.
- Personal tax thresholds are frozen for multiple years.
- These freezes are projected to raise tens of billions of pounds over the coming decade.
- The share of workers paying higher or additional tax is expected to rise sharply as a result.
- Frozen thresholds increase marginal tax rates for many ordinary earners.
So when people say taxes feel higher, they are not imagining it, even if the rate printed on paper has not changed.
What the “going part-time” claim gets right and wrong
| Claim | What the evidence supports | What it does not prove |
|---|---|---|
| “The economy is going part-time.” | Full-time employment remains far larger than part-time | No evidence of a mass exit from full-time jobs |
| “Because of Labour’s taxes.” | Reduced hours can come from many factors, not just taxes | Reduced hours can come from many factors, not just tax |
| Average hours have declined, and flexibility has increased | Fiscal drag is real and significant | Tax alone cannot be shown as the main driver of behaviour |
Why refusing a promotion can be rational
This is the part policymakers rarely say out loud.
Work more, keep less is a bad sales pitch.
Frozen thresholds mean a pay rise or promotion can push more income into a higher tax band. For a growing number of workers, the extra stress, responsibility, and time commitment do not feel proportionate to the take-home increase.
A simple example
- Salary: £49,500
- Promotion offer: £52,000
Because thresholds are frozen, a larger portion of that extra income is taxed at a higher marginal rate than it would have been if thresholds had kept pace with inflation.
The result is predictable. More work. More pressure. Less reward than expected.
That is not anti-ambition. It is arithmetic.
For some households, higher marginal rates also interact with benefits and allowances, creating situations where extra income barely moves the needle at all.
What you miss if you blame taxes alone
If you want a serious explanation for why people are easing off full-throttle work, tax is only part of the picture.
Other major drivers include:
- Post-pandemic reassessment of health, family, and time
- Normalisation of hybrid and flexible work
- Softer labour market conditions are reducing available hours
- Cost-of-living pressure is pushing households to protect stability rather than chase risk
If your entire story is “this is all about Labour’s taxes,” you are not analysing. You are campaigning.
A sharper conclusion and a warning for Labour
Labour can say it did not raise headline tax rates. That is technically true.
Workers can respond that their take-home pay still feels worse and that every extra pound earned is taxed harder. That is also true.
If Labour wants higher productivity and stronger growth, it cannot rely indefinitely on stealth mechanisms that quietly punish additional effort. At some point, people stop running faster on a treadmill that keeps speeding up.
Britain is not “going part-time” because people have become lazy. It is adjusting behaviour in response to incentives, pressure, and a labour market that has not felt normal since 2020.
Tax is part of that story. It is not the whole story.
