"A massive demonstration will be staged at CM Kejriwal's residence on January 27 in which a memorandum of our demands including regular salary, payment of arrears, regularisation of contract based employees, cashless health cards among others will be presented to him," said Sanjay Gehlot, president of Swatantra Mazdoor Vikas Sanyukt Morcha leading sanitation workers.
The sanitation workers and other employees of the three municipal corporation -- NDMC, SDMC and EDMC -- will also go on strike from January 27, he said.
He also claimed that not only sanitation workers but other employees of municipal corporations will join the strike.
The sanitation workers of the East Delhi Municipal Corporation (EDMC) had gone on a strike in October last leading to unhygienic conditions in that area due to huge amount of undisposed filth in the streets.
The strike was ended after the Delhi High Court intervened and directed the municipal corporation authorities to ensure disposal of garbage.
