I had a reasonably tolerable experience temping some years ago. I started doing it when I wasn't getting enough callbacks for permanent jobs. It was technically unskilled office work, but I was very attractive to temp agencies due to my typing speed. I didn't sweat the prospect of just being told not to come back the next day, but in practice this never happened - either I had assignments that had clearly defined start and end dates, or the places tried to hire me.
My last temp job turned into a pretty decent media job. As far as I could tell, there were two main reasons for them using a temp agency - one was that it was a way to get around corporate moratoriums on hiring. As time went on, people would get bought out from the agency either as contract workers (still due to corporate limits) or full fledged employees. The other reason was that it was a way faster process than actually interviewing & hiring people themselves - they were way too busy at the time to block out chunks of the week for that.
That said, before I ever talked to a single temp agency I was well aware of most of the forms of abuse possible (I think the Star used to cover the topic a lot in the 90's) and tried to be smart about it. The only problem I ever had was sometimes an agency would oversell your capabilities (but still underpay you)
