Dear Parikshit, Before giving a reply to your query, I need to provide clarification on the difference between an Offer Letter and an Appointment Letter. Once the employer is satisfied with the candidate's profile, the Offer Letter is given to the employee. This letter includes basic details such as the designation, salary breakdown, date of joining, etc. However, the utility of this letter ceases to exist once the candidate joins the company.
When the job candidate joins the company, they become an employee and require a letter that outlines the terms of employment. This letter is known as the Appointment Letter.
It seems that you are referring to the Appointment Letter and not the Offer Letter. Yes, provisions regarding non-disclosure of information can be included in the Appointment Letter. Regarding your second query on "employment contractual clauses," please clarify what information you would like to include under those clauses.
Thanks,
Dinesh Divekar
