I fully endorse the views of our learned friends Rajkumar and Saikumar expressed in the legal perspective. At the same stretch, I would like to add the following from moral and practical perspectives. Had you mentioned the reasons for inclusion of such a clause of condition in the appointment orders to the employees, it would have been easier for us to know your mind. Since freedom is the basic nature of all life forms, to be at the disposal of the other for whatsoever reason is the first constraint to freedom. But, one can not help it because interdependence is the inevitable feature of communal life. We have to bear in mind that mutualism or the relationship of organism in which each party is benefited by the other is the exact meaning of interdependence. Therefore, friction in relationship is the salient aspect of human association. Since an organization is a collective endeavour of the employer and the employees, the doctrine of survival of the fittest has no place there for the simple reason it is a place of co-existence. As long as the relationship is simple and just one-to-one, friction is less; but when it becomes one-to- many as in the case of an organization, friction becomes multitudinous and the most effective way of reducing it to fruitful interaction is again simplifying it to one-to-one i.e., the employer on one side and the representative body of the employees on the other. Here comes the emergence of employees' or workers' union as a parallel institution for grievance-ventilation and collective bargaining. There is nothing to be scared of employees' unions if the employer is law-abiding, considerate and magnanimous within his limits. After all, no one can chew more than what he can swallow!
