Until recently , I worked for a company with which I had signed an employment agreement . That agreement said that I couldn't solicit its customers for a year after I left , and that I couldn't ever use its customer information for my own purposes . One of the company's customers was a firm called , let's say , XYLIA . I knew of XYLIA before I ever came to work for the company I just left , and I had contacts within XYLIA that I developed way beforehand . I now work for a new company that competes with my old one . XYLIA wants to leave my old company and become a customer of my new employer . Can I get sued if XYLIA follows through with this ? Isn't it okay for me to share what I know about XYLIA with my new employer , since I didn't learn it while on the job with my old employer ?
