10.5% of UK Workforce are Underemployed

The Office for National Statistics have said that now over 3 million people are underemployed. This might mean they are doing a job that they are over qualified for, or more commonly they are working only part-time when they would prefer to work full-time. Most part-time workers are people returning to the job market after a period of unemployment or time away from the job market e.g. maternity leave. With more people in part-time employment, this means that the government is receiving less in tax and workers disposable income is decreasing.
