Can I sue my former employer for wrongful termination?

You should accept unemployment. From the brief facts you stated you don't have a legal claim for a lawsuit. Wrongful termination is a little bit confusing because employees who were fired for a wrong/unfair reason think they can take legal action against their employer. Instead, employees must be terminated for a reason that violates the law. Not fitting in or not being a good fit are not unlawful reasons for terminating an employee. Unless, you were discriminated against because of your age, race, disability, religion, pregnancy, color, national origin, etc, or you were a whistleblower or you were retaliated against for doing something like filing for workers' compensation or opposing discrimination, then you likely don't have a legal claim.   Accept the unemployment benefits and find another job. If any of the things I said seem like they are applicable, then you should contact an employment attorney.   Ohio employment attorney www.mcoffmanlegal.com
