Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
If you have proof of your good evaluations and proof of your negative drug tests, your first step is to file a grievance with the employer IF they have a internal grievance process. If they do not have an internal process, your first step is filing for unemployment
and you will have to file an appeal and go to the hearing and present your evidence, you absolutely should use an unemployment attorney on the appeal. Unemployment attorneys do not charge up front, they will charge a small percentage of the benefits you win, but it is worth it in the long run because if you make even a small mistake on an appeal hiring an attorney later may not fix the problem
The third thing is if you know who did this to you and filed the false claim
, you have a right to sue them for defamation for making known false statements against you and seek damage against them personally.
As far as being paid your PTO, unless the employer has a policy to pay PTO on termination
, under FL law it is not required for the employer to do so I am afraid. So that would be dependent upon your employer's policy and also proving that the reason for the termination was false or based on false information.
You need to take each of these actions if you want recourse.
