sanitary workers were asked to work only through contractors with effect from 01.02.1994. The contract itself is a camouflage. The Government, by G.O.Ms.No.2082, Labour and Employment Department, dated 19.09.1988, has prohibited contract labour in the process of sweeping and scavenging in establishments/factories. Since Slum Clearance Board has transferred approximately 400 employees to Chennai Corporation, Chennai Corporation has to count the services rendered under Slum Clearance Board and grant all benefits as if their services have been regularised under Slum Clearance Board. The Government has ordered for transfer of conservancy work and by that the so called contract sanitary workers have been transferred to Chennai Corporation vide order, dated 31.08.2005. Management Witness – M.W.1 has admitted that members of the Union have been working under six divisions of Tamil Nadu Slum Clearance Board with effect from 01.01.1986, but, however, on contract basis. After the contract period is over, they have no right to continue in service. By means of G.O.Ms.No.41, Municipal Administration and Water Supply (MCI) Department, dated 28.03.2005, which was marked as Ex.M-4, the Government has approved the proposal of transferring the conservancy staff and transferred all workmen from Tamil Nadu Slum Clearance Board to Chennai Corporation. Since their request for continuation of services did not yield any result, they had to make a demand for permanency and other benefits, which was referred to by the Government vide G.Os., mentioned supra, after the conciliation failed.
