I have worked for a small business for nearly two years and they are having me sign a second Employment Agreement. I signed the first one without offering changes because I desperately needed a job. With this one, like the last, they are maintaining their right as per the state of Ohio to hire me "at-will." The issue I have with this is that they are also including a non-resignation clause that prohibits me from leaving for any reason for 18 months, and allowing them to seek damages in the amount of their choosing, regardless of why the employment was terminated. There is no written guarantee of employment for that time, only vague statements like, "we want to keep you." Would this agreement be valid, or like I seem to have found elsewhere, "invalid for lack of mutuality"?
