Nobody at AVVO can help based on what you've told us. You are evidently an at-will employee, so you can be fired without any reason as long as you are not a member of a protected group against whom it is illegal to discriminate, e.g., gender, age, race, creed etc. You should find that great lawyer and tell him what the basis of your claim is.

"Wrongful termination" doesn't mean what it sounds like. It's a term used to mean termination in violation of anti-discrimination laws (which protect employees from discrimination due to their age, race, gender, ancesrry, religion or disability) you, or in violation of public policy, such as retaliation for "whistle-blowing." It doesn't mean mean termination that the employee thinks is wrongful.
Most employment in the U.S. is "at will," which means that the employer can fire the employee at any time without notice for any reason, whether confidentiality is breached or not, and no, they don't need a good reason, or any reason.
If you had a written employment contract, or there was a written contract re: conifdentiality, you may be able to make an argument that the company violated its own stated policies, but it's difficult.
Prepare a chronological list with names and dates of everything you experienced and witenssed (with 3rd party witnesses as well) and take that and your confidentiality contract to an employment ilitigator to fully disclose and discuss your situation.
