On another tack, the staffing office in the library just called me to tell me I can't go back to work on Monday without a doctor's certificate and I can't get one of those without an appointment. Given that the surgery is closed for lunch and it's Friday what are the chances of me getting an appointment before Monday? Pretty much zero I think.
So despite the fact that I'm on the mend, I might not be able to go back to work any time soon. How randomly strange is that?!
