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 present company. I have changed their PF account to new company and also date of joining also changed. Now the employees are asking while gratuity calculation date of joining is required old date in pay Slip. But I said that It's not possible to change the date of joining in another company and I shall give one letter stating that at the time of retirement we will give gratuity by calculating actual date of joining only. But the employees are asking one letter. Can you guide me in this regard.
