There is no statutory limit on the age of retirement on superannuation in the private sector. Any statutory provision in this regard, like the one found in the model standing orders under the IE(SO) Act of 1946, is only a guiding factor. It is for the concerned employers and the employees of any particular industrial establishment to decide the age of superannuation by consensus, taking into account factors like the nature of the jobs, passing through annual physical fitness tests beyond a certain age, etc.
