The Warsaw Tenants Association (WSL) is a tenant-run union founded in 2007 in order to defend the interests of public housing tenants. Initially, WSL organized against mass rent increases and evictions caused by (re)privatisation. Last winter, WSL launched a campaign against the high costs of heating in the city's South Praga district. In March 2011, Jola Brzeska, a founding member of WSL and one of its leaders was kidnapped from her house and mudered. Her case remains unsolved. Kinderbetreuung vor Ort.
