Sir, I am running two companies and I am planning to close one company. In that company, nearly 50 employees are there. Now I want to transfer all those company employees to the present company. I have changed their PF account to the new company, and also, the date of joining has been changed. Now the employees are asking why the old date of joining is required in the pay slip for gratuity calculation. I explained that it's not possible to change the date of joining in another company and I shall provide a letter stating that at the time of retirement, we will calculate gratuity based on the actual date of joining only. However, the employees are requesting a formal letter. Can you guide me in this regard?
