This report presents the findings of a survey of just under 2000 mothers with children under 10 conducted by the Resolution Foundation in partnership with Mumsnet, the UK's largest website for parents. The survey asked mothers about their preferences for work and their likely responses to hypothetical changes in childcare support. The survey was conducted over two weeks in November 2013. The first section of the report looks at maternal employment in the UK and identifies the specific areas of employment where the UK falls behind the best performers in the OECD. The second section presents the full findings of the survey, highlighting reported use of childcare, existing barriers to employment and mothers' perceptions of how their work patterns would change if childcare support were extended.
