No employer will grant you an employment contract in this economy. All an employer needs to do to replace you is pay out a few hundred dollars to train someone new and POSSIBLY pay you a few thousand dollars for severances (if they are somewhat kind). All-in-all, the few thousand they will pay to replace you is peanuts in the vast scheme of things. Since the employers have the upper-hand, by far, unless you are going for a management position (think CEO, CFO-something with a unique skills, like others have said), it wouldn't make sense for them to have an employment contract with you; it's far easier for them to replace you than it is for you to find a new job.
I wouldn't even ask about a contract, since that might look bad; it might look like “i'm worried that you'll want to get rid of me for some reason.” They probably wouldn't do this, but there is always the chance they would just go with another candidate applying for the job, if you did end up asking and pushing for one too hard.
I was at a firm for 6 months, before they got rid of me out of nowhere. Believe me, human capital is expendable these days, unfortunately. The employer easily has the upper hand.
The other exception is government positions (think IRS), which typically do have contracts. One of the few benefits of these jobs is the relative stability.
