Professional Biography

WWL says

Changsoo Jin is lauded extensively by market commentators as “a specialist in labour lawsuits” who does “great work and provides an excellent service”.


Mr Chang Soo Jin is a senior partner and co-head of the labour and employment practice group at Lee & Ko. Prior to joining Lee & Ko, Mr Jin served as a judge in various courts for more than 21 years, including two years as a research officer of the Korean Constitutional Court. Mr Jin’s practice encompasses a wide array of substantive legal matters from civil to criminal as well as constitutional law.

During his judgeship, Mr Jin mainly presided over labour/employment cases and built his expertise in both types of labour/employment litigation in the country’s judicial system – administrative proceedings to review the lower tribunal’s ruling and civil disputes between litigants. Mr Jin played a pivotal role in a number of landmark decisions that directly dealt with key labour/employment issues – including ordinary wage disputes for specific types of employees (eg, airline pilots, steel plant workers), low performance as termination grounds, and industrial actions by labour unions – which have had a critical impact on this area of practice.

Since joining Lee & Ko, Mr Jin has successfully expanded his practice to corporate/workforce restructuring and labour-management disputes. Outside his practice, Mr Jin has served as an adjunct professor of Ewha Women’s University and a legal advisor for the Ministry of the Interior and Safety. Mr Jin has also been an active contributor for multiple publications in the field of labour and employment law.

In the recent years, Mr Jin has won many notable accolades from ranking authorities, including his selection as a leading individual in labour and employment by The Legal 500 Asia-Pacific (2019), Hankyung Business Weekly (December 2018) and Chambers Asia-Pacific (2019).
