If you're not familiar with staffing agencies, some introduction is in order.
1) They take a cut of your pay, 40% or more -- e.g., if they give you $10/hour, they are probably getting $14/hr or more from the company for your work.
2) They do not give you benefits, though they offer a (typically bad) policy that you can pay extra for.
3) In my experience, they exaggerate the length of assigned jobs and play them up as much as possible. Remember, the recruiters are salespeople, and they're going to try and sell you the job so they can make some money.
4) They have so-called "buyout contracts" with employers, which is insidious for two reasons. First, if employers want to hire you full time (it does happen, but not as often as you'd think) they must pay a fee, usually a percentage of your first year's expected salary. In other words, they are penalized for taking you on full time. And secondly, this contract applies even after your temporary contract expires. That is, if you try to apply independently with the company after your assignment is done, the staffing agency contract still requires the company to pay the buyout fee, unless they feel like getting sued. This buyout period lasts 3-6 months.
My own experience with Remedy was decidedly mediocre. They found me work, yes, but the pay was lousy, and it lasted 1/3 as long as they projected. A week after I was let go a recruiter at Remedy emails me and says, "Your time card for last week is late -- please send it in as soon as possible!" Indeed, this kind of treatment/incompetence is what you can expect from both Remedy and staffing agencies in general.
