Dear Sir My last employer has shared me Certificate of Employment on my mail id after serving notice period and approval of resignation, and when I asked them if I should expect seperate document as experience and relieving letter they replied same document i.e certificate of employment will serve as both relieving and experience letter. so sir kindly confirm if it's correct or will I face any issues in future with this document? Note: this certificate of employment clearly says I worked from xyz date to abc date and it says I have been relieved from the services from close hours of abc date And in bottom it's mentioned : as per your contract of employment you will be bound by non- compete, solicition, non disclosure etc I am worried why my last employer have me certificate of employment instead of relieving letter and will it affect me in future?
