Dear Asmita, if the contract agreement is already in force and it is a fixed-term contract, then there is not much to write. You could have drafted just a two-sentence letter and uploaded it here for correction. Anyway, you may check the following draft:
Date: -
To,
Mr _____________
Employee No ______
Non-renewal of the Fixed Term Contract
Dear Mr ___________,
Reference is made to Fixed Term Contract (FTC) No ______ dated ______ that this company has made with you. The said contract expires on ________ (date). Considering the administrative requirements, it has been decided not to renew the said contract.
You will be paid remuneration until the last date of the contract, i.e., __________. For smooth separation formalities, you are requested to hand over the charge of your position to Mr/Ms __________ and submit the handing/taking over certificate on your last working day.
Though the contract could not be reestablished, your contact details are preserved in our records, and should the need arise, we might approach you to engage your services.
Thanks,
Yours faithfully,
____________ (name)
Authorised Signatory
Hope the above draft suffices your purpose.
Thanks,
Dinesh Divekar
