Historical Context
The badge is associated with the trade union movement in Poland after World War II, during the Polish People's Republic (PRL) era. The Railway Workers' Trade Union (ZZK) was one of the key organizations associating railway employees, who were an important professional group in the socialist economy. The badge served as a symbol of belonging to the union and was worn by railway workers during that period. Enameled versions were often more prestigious or intended for functional union members, produced by well-known engraving workshops, such as Iwańczak.
