Thank you for allowing me to assist you. Please keep in mind that I am answering your questions according to how the law actually applies to your case, not how one might wish it applied.
Cleveland Clinic has not broken any labor or employment laws, and you have no legal recourse against them for anything you described.
As an at-will employee (which you are unless you have a contract or union agreement), you can be terminated for no reason or any reason, even an unfair or bad reason. The exception is that you cannot be terminated for an illegal reason. Illegal reasons to terminate and employee include discrimination based on race, gender, religion, age and disability. It is also illegal to fire someone in retaliation for a legally protected act, such as taking FMLA or whistle blowing.
You were fired for a bad reason or an unfair reason. When this happens, your recourse is that you are eligible for unemployment benefits. But it is perfectly legal for your employer to fire you for a bad reason even if you are the best employee they have ever had.
I am sorry, I know this is not what you hoped to hear. But this is the reality of your situation. My policy is to just give the truth, rather than give false hope, only for it to end in more frustration for you later. I am only relaying how the law works to you, I didn't create it, please don't shoot the messenger.
