Thanks for your reply. I can get the scans done locally, but I can schedule them for the end of an afternoon or early morning, thus taking the typical hour or so off for a medical appointment. But I don't know how to explain away a 2 day absence on a monthly basis. Good tip on checking with the union. When I'm back at school I'll also have a look around the various staff policies on our servers. However, I really don't want to have to tell them what I'm doing. Is it feasible to just apply for a two-day leave with the excuse 'medical procedure' and leave it at that?
