The position is slightly more nuanced than the "2-day rule" that is often discussed online.
The provision requiring payment of wages and dues within two working days of separation comes from the Code on Wages, 2019 and the corresponding rules. However, although the Code has been enacted, its nationwide implementation depends upon notification and operationalization by the appropriate governments. In practice, many employers continue to follow their established Full & Final (F&F) settlement cycles of 30 to 45 days, particularly where clearance processes, asset returns, leave encashment calculations, bonus computations, reimbursements, and payroll reconciliations are involved.
That said, an employer cannot indefinitely delay settlement. Once all exit formalities have been completed and there are no legitimate pending issues, the employer is expected to process the F&F settlement within a reasonable period. A delay of 35 days without any clear explanation is not ideal, particularly when you were initially assured that the settlement would be completed within 30 days.
As regards the experience letter and relieving documents, there is no uniform central statute prescribing a fixed timeline applicable to all establishments. However, employers are generally expected to issue relieving and experience documents within a reasonable period after completion of separation formalities. Unnecessary withholding of such documents can be challenged.
My suggestion would be to first send a formal email to the HR department and payroll team recording the timeline: your last working day, the assurance of settlement within 30 days, the subsequent extension of one week, and the fact that 35 days have now elapsed. Request a firm written timeline for release of the F&F settlement, relieving letter, and experience certificate.
If there is still no satisfactory response, you may consider issuing a legal notice and, depending upon your employment category and applicable labour laws, approaching the Labour Commissioner or the appropriate labour authority seeking intervention. Often, a formal legal communication is sufficient to expedite the process.
Therefore, while it is not entirely accurate to state that every employer in every case is legally bound to complete F&F settlement within exactly two days at present, a delay beyond the employer's own promised timeline without justification can certainly be challenged, and after 35 days you are justified in seeking a clear written explanation and immediate processing of your dues.
