I guess it depends on the clients, and if they feel comfortable about their being such a close relationship between the recruiter and candidate. This relationship is going to be personal to the recruiter, no matter how professionally they act. And if the recruiter does not disclose the relationship, I think that would be considered unethical.
Also, she might want to seperate her professional and personal life in case something does go wrong. It's bad enough when there are hard feelings/difficult situations from a client, but it would be worse if it involved your family.
My general opinion would be for the recruiter to have her brother work with another recruiter that she can refer him to.
Like Pam said. Why not?
A few weeks ago I sent my brother-in-law on a sendout. The next day I had to tell him he was out. It didn't really cause too much discomfort. Other than needing to dig into his compensation a little further than family members normally do......
I'm am IT recruiter and my brother is a Software Developer. I've placed him twice now, once with a scientific imaging applications author and in his last role with a major legal firm. I've always been completely transparent with clients when marketing his CV and no-one has ever had a problem with it. We've charged the same rate we would charge for anyone else - why wouldn't we? He's an excellent candidate :-)
Thanks guys/gals for all the feedback! I agree with you all. It can work, it can be uncomfortable, and yes I would concur that there are friends and family that I will work with and friends and family that I will refer to another recruiter. Just like any MPC I think the most important thing is can you work with them, can they work with you, it is always about relationship. :)
