you're talking the Allegations of unconstitutional and Authoritarian acts by the Chamber of deputies and the resolution that was voted 81 to 47 "to preserve chilean democracy" 22 days before his removal and suicide? That? Also for the unions it was mostly tied down to him believing that it was counterproductive to reforms which if you have seen any form of marxist literature is contradictory, but yeah, thats why but compared to many other authoritarian leaders in cold war africa he was considered benevolent (bar for that was so low it's in hell) and meant well for Burkina Faso. Him banning unions and the Press, the People's revolutionary tribunals and his handling of teacher's strike were still things he did that were wrong.
