Ok. The problem here is that severance is not legally required in any state when a person is terminated. The only way a person is entitled to severance is when there is a contract signed giving that person a right to it.
Now, severance can be negotiated for by an employer, typically when they wish to release someone and want it to be a clean break. That being said, this is an employer's choice and is not legally compelled.
Because you did not have a contract of employment your employer could legally terminate you at any time, with or without cause. This is called "at will
" employment. So, the employer doesn't legally need a viable or accurate basis to terminate. The fact that there was not a formal investigation doesn't make this wrongful or illegal termination.
The only way you have a wrongful termination
claim is if:
1. You had an employment contract
requiring good cause for termination.
2. You can allege that the basis for your termination was discrimination
due to your race, religion, gender, age, disability or recent FMLA use.
You haven't alleged any discrimination and you stated you don't have a contract, so you don't legally have a basis for wrongful termination.
You also stated you don't have a contract for severance, so you legally don't have a basis for that either.
