Our Pro Bono activities

BKB is dedicated to the principles of diversity and inclusion in terms of promoting and implementing these concepts among employers.

Respect for equality should be essential for all organisations, regardless of size, and this is related to fundamental human rights. As this aspect becomes increasingly important especially in the era of high mobility and multiculturality, it requires constant attention and understanding, both on the employment and the social level. The leader of the inclusion and non-discrimination campaign is Daniel Książek, who personally supervises these processes and who strives to raise general awareness of diversity, inclusion, and counteracting racism and exclusion. To achieve this aim, he cooperates (on behalf of the JU) with units of The Clooney Foundation for Justice in court proceedings related to human rights.
