Dear Ms Blair,
I have the pleasure in informing you that the Appointments Committee for Departmental Computer Officers has agreed to reappoint you as Computer Officer Grade III in the Department of Engineering with tenure from 1 September 2006 to the retiring age.
Hurray! At last.
NB: despite the fancy language this just means I'm now a permanent member of staff, rather than on another short contract or not having my contract renewed at all. Normally it would happen almost automatically after your initial contract runs out, but because I was ill it's been much more uncertain for me.
