The functioning and survival of sports clubs depends to a large extent on their ability to recruit and retain the volunteer staff with whom they carry out their day-to-day operations. This paper examines the initiatives undertaken by Spanish sports clubs for this purpose and the organizational resources that condition the implementation of such initiatives. The empirical basis comes from a sample of 433 clubs. Categorical principal components analysis enabled the classification of initiatives for recruiting and retaining volunteer staff into four groups: economic, relation, formal and informative. Categorical regression analysis revealed the differential influence of size, age, economic capital, professionalization, habitat and democratic culture on each of these groups. The findings of the present study have implications for the management of volunteering at Spanish sports clubs.
