An employer who wishes to do something about consensual relationships between employees has a couple of options. The first is to implement a no dating policy. So long as the spouses dont supervise one another, a no dating policy enforced against spouses would violate this law.

Do federal and state laws require employers to regulate workplace dating?

Regulating relationships between employees is legal in most states, but it is important to check the local labor laws in your state before enacting a policy. Additionally, the way that you choose to regulate your employees relationships can have unintended consequences.
