It is hard to say exactly how it will affect your future employment, but it is clear that in today's competitive workplace that a potential employee without a criminal record may have a leg up. The offense is minor, and you do not have any other criminal history so you should discuss your options with a local criminal defense attorney.
You may be impacted negatively. You can hire a lawyer to expunge but remember you only get one in Florida!
