Hello people, I was working with a company, but I had to quit in August and rush back home due to some family problems. Therefore, I could not serve the 30-day notice period. Now, I have been offered a job in a reputed MNC. I am going to join them soon, but they have requested the relieving letter from my previous company. When I informed them about my departure, they mentioned that they at least need a resignation acknowledgment email from my previous company. However, when I contacted my HR for the same, he outright refused and is not even answering my calls. Now, I am in a difficult situation. If I don't receive any acknowledgment from them, I may lose this job offer, and it could potentially harm my career. I am feeling restless and tense. I would appreciate feedback and suggestions from all of you on what I should do. Please, guys, help me.
