I worked in a company for five years, from 2011 to 2016. Every two years, they renew their employee contracts and give a new contract to their sister company, so I don't know about the gratuity. Earlier, I was not paid a gratuity by my company. I have a 5-year experience letter from my main company. Three years later, I rejoined and continued with the same company, completing my five-year tenure in February 2024. If I leave this company, I should get gratuity for last five years and current five years
