Should I contact an attorney for wrongful termination?

My former employer discharged me for reasons that were fabricated. I believe this was in part because they were changing my working hours which I was against . I was awarded unemployment benefits. I have 2 letters written by current employees stating that the employer spent 3 days asking other employees questions in an attempt to justify their actions AFTER I was discharged. Their fact seeking mission should have been done before they fired me. Also they have a specifically outlined disciplinary procedure and policy, which they did not follow. If their accusations were correct, I should have received a verbal or written warning, not been terminated. I have the employee handbook and a copy of any disciplinary action I recieved while employed there
