KOR sent open letters of protest to the government and organized legal and financial support for the families of political detainees.
The group worked with sympathetic lawyers to get better representation for striking workers and obtained medical diagnoses from doctors which they presented as evidence of police brutality in court trials.
It printed material critical of the regime and reproduced banned writings from thinkers and writers outside of the Warsaw Pact countries, such as George Orwell.
In the fall of 1977 KOR collaborated with Warsaw intellectuals to establish the Flying University, a series of lectures organized by unofficial student groups to discuss ideas about freedom that could not be debated in public.
However, KOR became an inspiration for the nation as its efforts finally paid off when the Polish government declared an amnesty for jailed strikers in the spring of 1977.
