I recently filed a sexual harassment report against a postal worker who works in my office building. I am concerned that, whenever my company has sent me a paycheck in the past, this person has had access to my home address. I have already asked my office to start sending my checks to a PO box, but it may already be too late for that. Are there any avenues through which I can protect myself besides just locking my doors and being extra careful on the way to my car?
