Alleging that GO 279 was issued to hand over sanitation work to big contractors, GVMC Contract Workers’ Union went on a dharna at the corporation and ward offices on Thursday.
Sanitation, water supply, lighting and park workers, drivers and outsourcing and contract workers participated.
Union honorary president P. Venkat Reddy said if the GO was not cancelled workers would resort to indefinite stir.
He said the cadre strength decided when the population was four lakhs and the extent of the city was 110 sq km. Now the city was spread over 600 sq km and population was 20 lakhs but the number came down to 3,400 from 4,000. It was the effort of workers that achieved third place in the all-India cleanliness survey, he said.
