2.1. According to the case of the Management, the workman was purely engaged on temporary basis and the tenure would end at the completion of the project. In other words, the engagement was based on project basis and once the project concludes, the workman has no right to ask for continuance in the employment. According to the Management, the workman was engaged on NMR basis, on and from 25.03.1985, as Watchman. After the project was over, he was not employed further. He is only discharged from service and not dismissed from service. Only for the purpose of Thiruvannainallur Project, he was assigned duty and after the end of that project, he was discharged from service on 28.02.1991. Therefore, in the absence of proof to show that in the period of two years, the workman was engaged for 480 days continuously, the case of the workman will not stand scrutiny to law. Therefore, the order of disengagement / order of discharge passed by the Management has to be upheld.
