In recent years, hybrid organizations have been spreading in the competitive landscape, combining characteristics from both private and social sectors. To be successful, they need to do a great job managing limited resources. To this end, an effective operations strategy must be at the core of their priorities. Most of these organizations often rely on volunteer work to conduct their activities; therefore, mobilizing and engaging volunteers on a continuous basis is a key issue for many hybrid organizations. The present chapter aims to identify relevant workforce management practices in hybrid organizations. Building on the literature, the chapter offers a presentation of the main concepts underlying the setup of an operations strategy, highlighting the main particularities and challenges faced by hybrid organizations, and focusing on workforce management decisions. The chapter then identifies and discusses three workforce management practices employed by two hybrid organizations, whose operations are based on volunteer work.
