Hello. I worked for a PSU from February 2019 to June 2023 as a fixed-term employee. My contract was for 5 years, but I resigned and left after a tenure of 4 years, 3 months, and 12 days. Am I eligible to receive gratuity on a pro-rata basis as a fixed-term employee? If yes, which clause, rule, article, or law should I quote to my previous employer for claiming gratuity? Please help.
