I have always advocated for human rights and equality throughout my personal and professional life. Being raised in a more conservative environment made me understand my sexual orientation quite late. That made me see how important it is to be able to be your true self and the effect this can have on your mental and physical health. In the first years of my career, I felt insecure being out at work, thinking that others might misjudge me. This feeling was a common belief for other LGBTQ+ colleagues, and thus we decided to become more vocal about it. In May 2021, we launched the PRISMA working group within our organization. PRISMA advocates for a work environment that respects, welcomes, and supports lesbian, gay, bisexual, and transgender professionals, enabling them to perform to their fullest potential and contribute to Robeco’s greater goals. PRISMA serves as a support group and safe space for LGBTQ+ employees, advocates for equitable policies and benefits, and enhances Robeco’s visibility as a leading employer and asset manager of choice. Through external partnerships, internal training, and social/networking events, PRISMA enables all employees to become allies to their LGTBQ+ network inside and outside the organization.
I am proud to be a Project 1000 role model because I believe that visibility is a key driver to bringing equality and creating a more inclusive culture in our society. Showing your true self is scary, but it can also be deliberating and inspiring, or help others who might be struggling with their sexual identity and facing depression and anxiety. When you feel free to be your authentic self, you can flourish at work, build deeper connections with colleagues and fight discrimination that ultimately will benefit everyone.
