Football is one of the most popular organized leisure activities, and sports clubs organize many volunteers. But participation is stratified, volunteering among parents is class based and especially immigrant girls participate less. The aim of this study is to explore volunteering for children's football as a social activity from a relational perspective. We analyse the dynamics in the clubs to understand how structures are shaped in interaction between individuals and organizations. The study has a mixed-methods approach with interviews among club employees and a survey to volunteers. Our analysis reveal that the dynamics of the recruitment process results in a homogenic group of volunteers from a more affluent area and that flexible working hours is a key mechanism in the stratification process. Even so the playing children seems to be a more heterogenic group and especially boys seem to be recruited from a wider community.
