One-in-ten UK employees want to work more hours than they are currently able to.
Figures from the Office for National Statistics highlights the scale of the underemployment problem facing the nation at present.
With around one-in-four people in part-time jobs in need of additional hours, many families may be struggling to get by.
Indeed, between 2008 and 2012 the number of individuals looking for more shifts increased by one million, which shows how the economic downturn has affected the employment situation for some people.
East Midlands, Yorkshire and the Humber and the north-east were picked out as the three regions with the worst underemployment problems.
School crossing assistants and bar staff are the two occupations struggling more than any others to find enough hours.
Andrew Sissons, researcher at The Work Foundation, stated the statistics highlight how serious an issue underemployment is.
"Not only are underemployed workers struggling to make ends meet, they are also increasing the competition for jobs, making it even harder to reduce unemployment," he added.
