DH applied for a bunch of jobs and I told him about this company to look up, although he forgot to do that. So a staffing agency calls him, one that he applied to, and tells him about a position and the company and asks him if he has heard of them. He says No. However it's the company I told him about. So I look the company up online for DH and find the position listed on the website. I told DH apply to the main company and forget about the staffing agency. He is concerned that he has an obligation to this staffing agency now, since he told the guy he didnt' hear of them before, even though he did. So my question is, does he have an obligation to them? There was no contract signed or discussion of any contract. What do you think?
