As a global future-facing law firm, diversity & inclusion are not just aspirations for us – they are an imperative. We are committed to fostering a supportive and inclusive culture that encourages authenticity and celebrates all our people and their unique backgrounds. As they are central to our culture, we ensure that diversity and inclusion are at the forefront.

Our aim is to build a culture of trust, respect and inclusion which embraces differences and encourages diversity of people, views and experiences for the benefit of all.

Our D&I strategy, Future Facing Inclusion, is a way of thinking and being. It brings together everyone at CMS, as well as our clients and communities, whatever their backgrounds, to develop thriving careers, positive cultures and new ways of working. It is a force for change.

Diversity & inclusion is championed at the senior level across the firm. Our Managing Partner, Andrzej Pośniak, is a great advocate for D&I and champions it internally and externally to ensure that CMS drives change not only for its people and communities, but also for the legal sector and the wider business community.

As for our D&I initiatives, once a year we organise the CMS Diversity & Inclusion Festival to celebrate differences, to keep this essential debate going, and to share our experience and knowledge. Moreover, in Poland we regularly join in the organisation of anti-discrimination initiatives, including meetings with the Polish Ombudsman, non-governmental organisations, leading Polish reporters and law students. In striving for gender equality, in 2021 we also partnered with the CFA Society Poland to release a report entitled “Women on boards and company performance”, which is aimed at verifying the view that gender equality is associated with better financial performance, lower risk, and a higher market valuation.
