Dual employment - One my colleague forgot to offboard an employee after giving resignation confirmation

Hi All, I have a serious query please help. One my colleague forgot to offboard an employee after giving resignation confirmation via email to the employee. The employee was onboarded with the client on their payrolls basis email confirmation shared by him. Resulting in dual employment. Payroll, PF everything is active in both the company. How can this be corrected? Please guide..

It is the mistake made by the organization which accepted the resignation and relieved the employee concerned by not documenting the fact in its own internal records. Therefore, there is no dual employment in fact but for the omission in the records of the previous organization. Besides, payment of salary and statutory deductions there of would have been made only for the period of service rendered by the employee in the organization only.
Thus the only option to remedy the situation is correcting the records of the poster's organization accordingly.

This issue can be corrected internal by the 1st organization. Not sure how the corrections will happen in PF department where contributions are made from both the employers, resulting duplication.
