[FL] Anti-Vax Emails Sent to Employees

Is it legal for an employer to send anti-VAX emails to employees encouraging them to reconsider, vaccinating their children based on a biased and flawed study linking vaccines to autism.

Said email was a link from x.com of a guy posting about a study that was found to be biased, flawed and posted on a WordPress blog, not in a scientific journal. My concern is the misinformation being spread and whether this could have legal implications especially if influences employees, health decisions.
