It's fair to say that there's a lot of gray area when it comes to business relationships, especially when they end. Part of the reason for this is that many employees are employed in an "at will" status. This means that the boss can fire them whenever he or she wants to do so, and there does not even have to be a reason.
For example, a boss could just not like working with an employee or not appreciate the way he or she gets along with the other workers. The employee can then be fired and replaced, even if there was not any major reason—just a string of minor annoyances.
It's important to remember, though, that even an at-will firing with no reason whatsoever—or at least, where no reason is given to the employee—can't be done in a discriminatory fashion. Just because the boss does not have to tell the employee why he or she is being let go doesn't mean that the reason can be that employee's age, gender, race, religion or anything else of that nature. To fire someone based on those things is still illegal under federal law.
This does mean that a wrongful termination in Florida can be complex and confusing, which is why it can be so important to have proper legal assistance if you think this has happened to you. Your employer is most likely not going to come out and tell you why you're being fired, seeing as how that is not always mandatory, and so you and your legal team must work to show how discrimination played a role and why you were really fired.
