Because when I've asked them about the reputation of temp agencies, they insist that all employers do the same things they do. Some examples are: Lying about the job, lying about pay, poorly matching someone to an assignment, refusing to place anyone who doesn't take the first job they present to them, believing whatever lies the client tells them about the temp, threatening to blackball people in the city so they can't ever work again. Those are just a few of the things they do.
