Dear Management,
Management cannot suddenly retire a workman. There needs to be a service condition to that effect lest it be termed as 'Retrenchment' under the Industrial Disputes Act 1947.
Retirement Clause and Procedure
Assuming the existence of a clause providing for retirement, be it Standing Orders, appointment order, or service condition communicated to the workmen, the order could read as follows:
On attaining the age of superannuation as per clause No. of -----------------, Shri ---------, Employee No. ----------, ----------(Designation), will be retiring from the service of this organization with effect from ..\/..\/.. (A\/N).
He will be paid his dues on submission of a 'No Demand Certificate' from the concerned departments as per the format attached.
