First question. If there is an employee that has an exgirlfriend ( brief relationship) thathas harrassed him in the past to where he changed his phone number and now the ex girlfriend has resorted to coming into his place of business (retail establishment)which she has never frequented before and doesnt physically harm the employee but makes loud rude comments or generally smarts off to him unprovoked is he within his legal right to ask her to leave and not return or would he be putting the business at risk in any way?

Second question. When working retail and you are the manager and money comes up short and you can by process of elimination pin it to one person but did not see it being taken, how far can you legally go in confronting the employee? What are the reccomended steps to take in a situation like this?

This is in Indiana. I dont know if the laws for either of these questions vary from state to state.
