I already have a part time job that I am very happy with (3 days a week.) However I am currently going through a divorce and as a result need an extra day, maybe 2. I don't want to leave my current position but want to find another part time job to make up the hours. But there aren't many part time positions in my field of work in the local area. WIBU to apply for full time jobs with the hope that I will impress them enough at interview that they will be able to accomodate me in a job share role? Or is that just completely wasting the interviewer's time?
