Keeping accused pedophiles on the payroll is not a good look when the company is trying to disprove rumors that they are a company full of groomers, no matter how unfounded those rumors may be.
Law enforcement can't bring someone in based on a hunch. There has to be probable cause. That evidence alone should be sufficient for termination of employment. They can certainly have their job back if somehow it comes out during the trial that even the probable cause evidence was inaccurate (for example, they accused the wrong person entirely), but that is highly unlikely.
ETA: Even if someone is found not guilty, it doesn't mean they are entirely innocent either, and the standard for someone losing their job is much lower (and subjective), especially in an at-will state such as Florida, than a criminal conviction.
