Thank you for using JustAnswer.
I'm very sorry to hear about your situation. In terms of an employment law scenario, that is correct. There are certain threshold requirements for certain types of cases. Sexual harassment cases under Title VII have a 15 employee minimum requirement, as do the state laws no the matter. But criminal harassment / stalking cases are criminal in nature, and that could still be brought against the board member himself. Contact the police, and save any type of information that you possibly can that would prove this stalking.
The main issue here is that the employer isn't going to be liable in a civil action against them. It's frankly not an "employment law" situation because the minimum threshold for employees is not met. You can still bring a civil action against the board member himself, as well as criminal charges and a restraining order. Those are, I'm sorry to say, your only options.
I know this is probably not what you wanted to hear, but it is the law. I hope that clears things up anyway. If you have any other questions, please let me know.
