My niece's husband quit a job recently. He had a non-disclosure agreement with the company. He is now working as a self-employed contractor. Today he received a letter from a lawfirm demanding that he stop sharing his former employer's information and giving him one week to affirmatively state that he is doing so. He's not sharing information with anyone. It seems to me that this is simply an intimidation tactic. They don't have the funds for an attorney at this time. What should he do next?
