About us

BKB Baran Książek Bigaj was founded in 2006 as a continuation of several decades of practice of the distinguished expert in Polish and international labor law – Professor Andrzej M. Świątkowski, PhD., hab., and over ten years of practice in labor law of Daniel Książek, PhD., hab. – the founder of BKB. In 2017, another renowned labor law expert, Professor Krzysztof W. Baran, PhD., hab., joined the team. He is an undisputed authority in fields such as collective labor law, and the editor of over ten volumes of the prestigious series “System Prawa Pracy” (The Labor Law System) (Wolters Kluwer).
Our law firm is ranked second in the most prestigious “Rzeczpospolita” ranking of law firms in Poland for labor law and social security, and Daniel Książek PhD was named among the leaders (second place) in the same category.
We were also named among the top law firms in Poland in ”Forbes” in 2022 (labor law category).
As most of our lawyers combine the practice of law with academic work at the Faculty of Law and Administration of the Jagiellonian University and other national and foreign universities, we offer legal services of the highest possible quality.
Our experts have participated in fellowships and exchange programs organized by universities such as the University of Pennsylvania, Harvard University, and Columbia University.
We specialize in Polish and European labor and social security law and provide comprehensive legal services at the highest substantive level in these areas. BKB Baran, Książek, Bigaj advises the largest firms operating in Poland.
We advise on the most complex, challenging employment law cases, including industrial relations and employment litigation, and cases before the Supreme Court.

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.
