1) You do not owe her boyfriend anything whatsoever--you don't even need to talk to him and should NOT talk to him about her or her employment. The next time he tries to call, simply say it is not appropriate to speak to a non-employee about an employee, say "good bye," tell him you are hanging up now and then hang up.2) Have the employee sit down in an office with you and your husband and explain to her that she needs to keep her personal life, including her boyfriend, out of the business and that if she cannot or will not, you will have to terminate her. Let her know that if her boyfriend contacts you or your husband again, she will be terminated. Give her a written summary briefly stating that she understands and acknowledges that a person with whom she is in a relationship cannot contact your company, or any of the owners and managers, and that if such a person does, her employment will be terminated. Have her sign the form to show her receipt of it and keep a copy. If she won't sign, terminate her on the spot.Then if he does contact you again, terminate her: otherwise, you are subjecting yourself to potential future harassment from him.
