"Retirement age" or "age of superannuation" as it is called is the mutually agreed point of time at which the contract of employment between the employer and the employee comes to a peaceful end. Such an age is fixed in the contract of employment taking into consideration of several aspects like the nature of the job, general physical fitness of the employee, general practice followed in similar industries in the region or country etc. There is no special law exclusively for this service condition other than the Industrial Employment (Standing Orders)Act,1946 which too lays only guidelines for the aspect of the age of superannuation of industrial employees to be fixed and followed uniformly. However, the employer has the prerogative of extension of the services beyond the age of superannuation with the consent of any employee. The employer has the discretion to fix a different age for his employees, if there are convincing reasons for such a move subject to uniformity of implementation.
