A U.S. appeals court ruled Friday that employers may stop their employees from fraternizing if it is non-work related, that is just for fun; but it cannot stop them from organizing or engaging in other concerted activities relating to work, such as unionizing.  Is an anti-fraternization policy a good idea?  My opinion is no, even if it is legal.  Employers may be tempted to prohibit employees from dating or socializing to avoid sexual harassment or similar claims, but I do not think it is effective way to reduce risk.  It is my belief that such a policy will not prevent romantic relationships and that the employees will feel that their employer is "big brother" and will resent the policy as well as all other less intrusive policies and it may create more problems than it solves.  I think it is best to be aware of situations that could cause problems down the road and to adequately train managers to spot potential problems.
