There Are 1.1 Million Underemployed Part-Time Workers in the UK. Here's the Strategy Most of Them Are Missing.

Underemployment Is a Persistent Feature of the UK Labour Market

The Office for National Statistics defines "underemployed" workers as those who work part-time and report that they would prefer full-time work but cannot find it. As of Q1 2026, the ONS estimates 1.1 million UK workers fall into this category — people who want more hours and more income but are unable to access the full-time positions that would provide them.

This form of underemployment is distinct from unemployment but shares many of the same financial consequences: lower income, reduced pension contributions, fewer employee benefits, and limited career progression. Workers in this situation often feel stuck — applying occasionally for full-time roles while continuing part-time work, receiving few responses, and concluding that the full-time market is closed to them.

In most cases, it is not closed. It is simply that the application strategy being used is not calibrated to the level of competition.

The Hidden Cost of Low Application Volume for Underemployed Workers

Underemployed workers applying for full-time roles face a specific challenge: they are competing against unemployed candidates who have more time to search, and against employed candidates who are using full-time experience as a signal of commitment. Neither of these advantages is insuperable, but they mean the interview rate per application may be slightly lower than average.

The mathematical response is higher volume: 35 to 50 well-targeted, tailored applications per month rather than five to ten. This is the pace at which the probability of generating three or four active interview processes becomes reliable.

The practical barrier is time: workers with part-time jobs, often combined with caregiving or other commitments, have limited capacity for a high-volume job search done manually. The tailoring process alone — 30 to 40 minutes per application at manual pace — makes 40 applications a month effectively impossible without tooling.

Why Tailoring Matters for Workers Moving From Part-Time to Full-Time

Many part-time workers underestimate the impact of tailoring on their interview rate. The assumption is that their experience speaks for itself and that the volume of hours worked (part-time vs full-time) is the main barrier. In reality, ATS systems do not know how many hours you worked. They screen for keywords and role relevance.

A well-tailored CV from a part-time worker who demonstrates deep, relevant expertise in the specific area the employer is hiring for will outperform a generic CV from a full-time worker with less specific experience. Tailoring removes the hours-worked disadvantage at the ATS stage.

CVCircuit for Underemployed Workers Seeking Full-Time Roles

CVCircuit's browser extension compresses the application process to under two minutes per role. Working part-time hours while running a serious full-time job search becomes achievable when each application takes two minutes rather than forty-five.

Applications are tracked, follow-up timing is visible, and the pipeline that produces full-time employment is built consistently even within the constraints of a part-time schedule.
