Although Brazil is a country with a diverse population, its corporations do not reflect this diversity, revealing inequalities, especially in positions of power. This is because the regimes of inequality created by companies serve to maintain the interests of dominant groups, thereby limiting the mobility of minorities and reinforcing disparities of class, gender, race, and so on. In this context, the present study sought to examine the ways in which the pharmaceutical company Herbarium seeks to promote diversity, equity, and inclusion (DE(and)I) within its workforce. This included an assessment of the company s key initiatives, as well as an examination of the facilitators and challenges encountered in implementing these practices. Asingle case study was conducted using a qualitative approach, utilizing document analysis and semi-structured interviews with eight key participants within the organization. The results identified the following key factors for initiating and sustaining the process of change in the pursuit of DE(and)I in the organizational environment: 1) the importance of literacy in raising awareness of inequalities; 2) leading by example to be followed; 3) active listening as a tool for diversitymanagement; 4) the need to review organizational processes; 5) setting clear goals; 6) the central role of the DE(and)I manager; 7) affinity groups as drivers of change.
