Magic Forums

Hello, I have a pest of sorts that is bullying my spouse at work and I don't want to cause any real harm as long as they leave him alone going forward. Does anyone know of a curse or spell that could be placed that would only effect the target if they do not change their behavior? I believe strongly in the rule of three so I know misfortune will come to this person but I want to send a clear message that if this continues to go on with my husband that it will no longer be tolerated. He works for a company that traditional methods do not go well for those who report these actions to say HR or their boss. I can not physically confront this person either as it would look bad on my husband, so this is my last resort not first. Anyway thanks for any help, sorry if this is in the wrong forum.
