Most clients require a guarantee, usually around 90 days. Sometimes pay terms are sooner, so theoretically you could have to refund a fee if a candidate leaves quickly and you don't replace them. In-house recruiters are not usually paid fees like agency recruiters - they might get bonuses, but most in-house are paid mostly in salary with smaller performance bonus. Agency recruiters are usually paid little (sometimes nothing) in salary with most comp coming via commission. This explains bad recruiter behavior, or at least much of it. Every deal might be 10-20K in the recruiter's pocket. For that amount of money, some people will do things they wouldn't normally do, and morals go out the window.
