A free guide. Notice periods cause more exit disputes than almost any other clause. Here is how they usually work in India. This is general information, not legal advice.
For most office and managerial employees, no single national law sets the notice period. It comes from the employment contract (the appointment letter), the company's service rules, or standing orders where these apply. Some state Shops and Establishments laws set minimum notice for termination by the employer. For employees who count as "workers" under the Industrial Relations Code, 2020, retrenchment generally needs one month's notice (or wages in lieu) plus retrenchment compensation. Check what applies to your state and to each category of employee.
Make the clause mutual (the same for both sides) and state it separately for probation and after confirmation.
Most appointment letters let either side end employment early by paying salary for the unserved notice period. Specify whether "salary" means basic pay or gross pay, because this is a frequent source of disputes. If the clause says nothing, there is room for argument.
You can choose to waive part of the notice period (early release), or ask the employee to stay away from work during notice while you keep paying them (garden leave). Both should be allowed for in the appointment letter and confirmed in writing when used.
The Code on Wages, 2019 generally expects wages due on separation to be paid within two working days of the employee leaving. Plan the handover so the settlement is ready.
The notice clause in our appointment letter template (₹199) covers probation and post-confirmation notice, salary in lieu (you choose basic or gross), early release and garden leave. The relieving letter (₹149) has wording for when settlement is still pending. All four letters: Starter Pack, ₹449.
