“Prosocial” organizations have an explicit mission to make a positive difference in the world, such as eliminating poverty, fighting racism, or improving health. Dr. Oelberger examines these organizations’ internal dynamics across the prosocial workforce, asking: what are the implications of prosocial work for staff wellbeing, non-work relationships, and careers, particularly in disparate ways based upon intersectional social identities? How do these processes influence the people prosocial organizations serve? She also examines these dynamics in grantmaking foundations, asking: How do the non-altruistic interests of grantmaking foundations influence their decision-making processes and funding decisions? How does this impact the equity and effectiveness of the prosocial work ecosystem? Ignoring these internal dynamics leads to deleterious outcomes, including workforce burnout and inequitable decision making, which end up harming the ecosystem of prosocial work.
