This chapter investigates the process of professionalisation within civil society elites, defined as the shift from unpaid voluntary engagement to paid employment within CSOs. Comparing Italy’s corporatist civil society tradition with the UK’s liberal model reveals contrasting dynamics. Italy exhibits lower levels of professionalisation, with a predominance of unpaid leaders and minimal reliance on salaried staff roles. In contrast, the UK’s civil society landscape demonstrates advanced professionalisation, marked by a higher proportion of remunerated positions and greater dependence on state funding. Leadership composition reflects these divergent trajectories. Italy’s elite predominantly comprises presidents aligned with political advocacy, while the UK’s leadership cadre features a stronger presence of directors embodying managerial expertise. Demographic analyses reveal greater diversity among the UK’s elite regarding gender, age, and education, suggesting inclusive yet socioeconomically stratified leadership pathways influenced by professionalisation. Qualitative insights from Italian leaders illuminate tensions between the merits of professionalisation in fostering meritocracy and apprehension about compromising the sector’s historical identity. This dichotomy underscores the delicate equilibrium between tradition and innovation within civil society’s evolving governance structures. Ultimately, this comparative exploration elucidates how professionalisation intersects with elitisation processes, power dynamics, and institutional biases, offering a nuanced perspective on civil society’s transformative role in championing inclusive leadership and equitable social progress.
