Dear Crish,
Yes and Agreed beacuse in your offer letter / appoint order based on that you will work on that then relieve there.Suppose if they ask again one month, please do it and complete the task then relieve that company. You hed been completed 2 years 1 month, then you why you have urgent to relieve. Please be polite and ask relieve that.
Because all mistakes from your side. Any company asking our original certificates, you dont give it and dont join there. Becasue that is illegal company. They will not follow company & employee laws, not treated employees properly. If you not get job that is not a problem and will start own business. But if you give your original certificates for job, that is your mistake and you are unskilled employee.
Please be form and polite to get original certificates and exp certificates.
