I currently work p/t .6fte as a band 6 but my pay spine overlaps with band 7 by a couple of points. I am going for band 7 job, .8fte. If I stay on the same pay spine I wont be much better off with the extra childcare and travel, so ideally I would like to go up a couple of points, but I don't feel confident asking. Has anyone done this? How did you negotiate it with your manager?
