Legal Question in Employment Law in Georgia

You don't tell us what you mean by "do something legally." Stop a potential stalker with police intervention? Make sure you still have a chance at the job? Sue and get a check?

If the first, if you have a reasonable fear of this, contact the police. If you want the job (and there is a question of why you would after this), you don't tell us whether this happened yesterday or 6 months ago, and there are other details such as size of the business, etc. If you want a check, you can probably see some lawyers who will pursue something like that, but if you are unemployed and need a job keep in mind the reality that other future employers will know if you pursued a lawsuit from a job interview (whether or not you have a valid claim).

If you simply want to get this behind you but at the same time feel it is important to see that this does not happen again, without potentially jeopardizing other job opportunities, contact the HR department or highest level manager you can find and report the details.

If you want to move on and put this behind you, not rock a boat or potentially anger anyone, you can do that too. Either way, do not respond to this man in any way, and save the messages.
