The study concerns how many hours per week were spent volunteering; some was paid, some was not, though presumably a single organization would either pay or not pay volunteers, rather than both. Paid volunteers worked less per week overall.
The study I referenced was not the one I intended to reference, but I have not found the one I most specifically remember. Citing studies is one of the things I most desperately want an eidetic memory for.
