Originally published in 1994, this volume analyses the relationship between political parties and trade unions in Poland, the Czech Republic, Slovakia, Hungary and Bulgaria. Political parties had high visibility in the changes that took place in Eastern Europe during the 1980s and early 1990s. Far less visible were the developments in the trade union sphere, where the old 'mass organizations' of the communist period, now independent, were joined by newly-formed organizations, and both played a central role in politics.
