Union of the Workers of Slovakia

The Union of the Workers of Slovakia (Slovak: Združenie robotníkov Slovenska, ZRS) is a radical-left party in Slovakia.

The ZRS split from the Party of the Democratic Left in 1994. In the Slovak parliamentary election in 1994 the party gained 7,34% of the votes and 13 seats in parliament. Although calling themselves "agrarian-left" the deputies entered the coalition of the national-conservative People's Party – Movement for a Democratic Slovakia and the nationalist Slovak National Party. The ZRS occupied the Ministry of privatization, to ensure that key industries remained under state control. Until today the ZRS writes on its homepage that it prevented privatizations in the gas industry, energy sector, telecommunications, banks and insurances.

On the international level the ZRS has no party linkages.

In the 1998 parliamentary election the ZRS received 1,30% of the votes. In 2002 the ZRS received 0,54% and in the 2006 parliamentary election it received 0,29%. In the European Parliament elections in 2004 and 2009 the ZRS did not run. In the 2010 parliamentary election the party received 0.24% of the votes - a poll estimated a possible range of 0,6% of the votes.

The President of the ZRS is Ján Ľupták.
