I work part-time for University in an administrative role and I am at the top of my pay scale. I've been waiting several years for a part-time job at the next level to come up. Every time a full-time job comes up I contact the Manager for that job and ask if I can apply but do the job part-time/flexibly and each time they say something along the lines of "this post needs to be full-time because we are a busy department etc etc.".
Last week I had an interview for a part-time job at the next level. I didn't get the job but the feedback from the recruiting manager was that I gave an excellent interview but that the field was outstanding. He then went on to express his surprise at the quality of the field and admitted that he hadn't want to create a part-time role because he couldn't be sure of the quality of the applicants. This is a senior manager in a world-class university who cannot see that there might be a pool of talent out there that can't work full-time. I fucking despair!
