As has been held in a catena of judgments of the Supreme Court in Manager, Reserve Bank of India, Bangalore v. Mani[1] , Batala Coop. Sugar Mills Ltd. v. Sowaran Sing h[2] , Surendranagar District Panchayat v. Dahyabhai Amarsin h[3] , Chief Engineer (Construction) v. Keshava Rao (dead) by Lrs.[4] Range Forest Officer v. S.T. Hadimini[5] , the burden of establishing that he had worked for more than 240 days in a period of 12 months prior to his termination is on the workman and it is only if this burden is discharged, would the burden shift to the employer. In the present case, the fact remains that the workman, who claims to have worked from 1976 to 1981, for the first time, addressed a letter to the Deputy Executive Engineer in 1986, 4½ years after his alleged termination. Neither the conciliation report marked in Ex.W.1 nor the letter addressed by the Deputy Executive Engineer to the workman in Ex.W.2, contains any admission that the petitioner had worked. All that was stated on behalf of the department before the conciliation officer is that the matter be referred to the Labour Court for its adjudication and that the employer was not inclined to reinstate the workman. In the letter dated 18-05-1986 addressed to the workman, marked as Ex.W.2, all that was stated is that the workman should approach their office along with his service certificates in proof of his having worked in the sub-division during the relevant period.
