I signed a bond with my previous employer while joining. I had issues with my previous employer re. working in shifts, salary increments and transfers. I got a better opportunity after working in the previous organisation. But while quitting the job, i didn submit any resignation letter. After 2 months they sent me a recovery letter and now after one yr they have sent me a bond repayment letter. Is this letter valid once as they sent me a recovery letter before sending the bond repayment letter..??
