Florida Senators will be requires to take an hour of workplace and sexual harassment training before the start of each legislative session.
The rule was adopted as the first business taken up when the Senate went into session on Wednesday.
The mandates comes after two senators resigned in the past few months.
Democrat Jeff Clemens stepped down after admitting he had an extramarital affair with a lobbyist. Republican Jack Latvala resigned after an investigation found that he likely committed acts of sexual misconduct.
Senate Rules Committee Chair Lizbeth Benacquisto told her colleagues that the chamber has a zero-tolerance policy for sexual misconduct and retaliation.
The Florida House already requires mandatory training for its members.
