My question now is, should i pursue a wrongful termination case against my former employer?
Based on all your posts you were not wrongfully terminated. I won't repeat what LG81 said since it would be redundant but will add that wrongful termination means you were fired for a reason prohibited by law, NOT that you believe your termination was wrong. Being approved for UI does not mean your employer broke the law it means that UI did not agree that your termination rose to the level of misconduct egregious enough to deny you benefits.
It is a common misconception that being on FMLA means the employer cannot fire you. The employer may fire you for any reason that would have caused your termination even if you were not on FMLA. If you would have been terminated for the conduct or laid off regardless of being on FMLA the employer may take that action. They cannot terminate you BECAUSE you used FMLA. It does not appear your employer did that.
I am thinking of consulting an attorney, but thought i would ask for some advice here before i go any further.
You can certainly call a few employment attorneys. Most will do an initial phone consultation at no charge and can tell you based upon the basic facts if there is the potential for a case and if you need to schedule and in depth paid consultation.
I have suspected all along that i was terminated for reasons other than the misconduct, and now that i have won my unemployment case i wonder if i should pursue this.
You will need way more than your suspicions to sustain a lawsuit. The burden of proof is on you to prove their conduct was illegal. They do not have to prove they didn't if you intend to bring a suit.
