The end of service gratuity calculation upon termination

Hi Ma'am,

I have worked for a company almost 12 years as an accounts manager, and the company decided now to outsource a finance team.

The outsourced company offered me a job and they will give me the same package, but I will be working in this company only for 3 months then I will be sent to other clients as well.

This is an Indian outsourced company and I have taken a decision that I am not willing to work with an outsourced company which is unknown to me.

I am working as per JAFZA visa for 12 years. The company gave me a letter with subject stating the cancellation of the contract and I will be served for 30 days notice period.

So, can you please explain to me how I will go through in this situation and what benefits will I get as per JAFZA rules and regulations?

Thanking you in advance for the help and I wait for your reply in this.
