Document D79, dated November 20, 1978, is a letter from Charter 77 spokespersons Ladislav Hejdánek and Václav Havel addressed to the congress of the French General Confederation of Labour (CGT) in Grenoble. The authors express their gratitude to the French trade unionists for their solidarity and support of the human rights movement in Czechoslovakia. The text references a previous meeting between Charter 77 representatives and a CGT delegation in Prague and commends the confederation's public stance against occupational bans. The spokespersons emphasize that despite persistent harassment from state authorities, Charter 77 remains active in its pursuit of civil liberties. The letter highlights the connection between the Czechoslovak struggle for freedom and the global movement of human rights defenders. It voices hope for continued mutual interest and solidarity while wishing the CGT success in their own endeavors. This document illustrates Charter 77's strategic efforts to establish international ties and secure support from influential Western left-wing organizations to bolster the movement's international standing and draw attention to the violation of the Helsinki Accords in Soviet-bloc countries.
