The usual requirement for most graduate jobs is a 2:1 degree and some kind of experience. Your average PhD student has a 2:1 degree and no full-time experience; your average regular graduate by the same age will have a 2:1 degree and 4-5 years full-time working experience, probably including several promotions. Unless the role is highly technical/specialised, the fact that you have a PhD is unlikely to sway the recruiter in your favour... unfortunately in this job market, as long as you meet the minimum academic standard, experience is what counts. I say this as someone who would have loved to do a PhD in my arts subject but didn't because it would have been career suicide.
