Uncovering patterns and policy implications of multiple employment

The project will provide evidence from the Annual Survey of Hours and Earnings (ASHE) with PAYE (Pay As You Earn) and Self-Assessment data from His Majesty's Revenue & Customs (HMRC) on whether multiple employment is due to financial and/or local constraints in the labour market, and how constraints vary by gender.

Dr Darja Reuschke received a research fellowship by the ADR UK (Administrative Data Research UK) to use new administrative data in the ADR UK’s ‘world of work’ theme. The project, running from September 2024 – March 2026, aims to increase understanding and raise awareness of multiple employment whereby individuals have more than one job or forms of employment. Little is known in particular about the phenomenon of mixing employee jobs with self-employment.

Objectives

The Annual Survey of Hours and Earnings (ASHE) is the most comprehensive survey of payrolled jobs in Great Britain carried out in April each year by the UK Office for National Statistics. By analysing ASHE linked with HMRC self-assessment and payslip data, the project aims to shed light on the prevalence and patterns of multiple employment, the financial risks involved, and how local labour market conditions affect these work arrangements. This research will provide valuable evidence to inform labour market policies, particularly around low-paid and casual work.

  1. To what extent are multiple job holding and combining employee jobs and self-employment linked with low-pay, low working hours, and casual or temporary contracts in paid employment?
  2. How do the risks and spatial patterns of financial constraints from combining a salaried job with self-employment, compare to those of employees with two or more salaried jobs?
  3. Who is most at risk of taking on an additional job or self-employment due to financial constraints in employee jobs, and are women at greater risk than men?
  4. What aspects of place are associated with financial constraints among employees with multiple jobs or additional income from self-employment, and do these vary for women and men?
