No, absolutely not. Some of our best cases are the result of employees calling us before they get fired. Properly documenting evidence regarding why an employee is being terminated is easiest to do while you’re still an employee. You must assume your employer will lie about the illegal reason they fired you, so you should preserve evidence before you are fired. You should talk to an attorney to understand your rights and how to document evidence before you are fired, so it is difficult for your employer to lie about what happened.
