Cryptic Clue's!!!?

Hi all, i was wondering if someone here can help me? On looking at our Rota board on the left hand side next to my name it states that i am a STD but others are SUPN. Don't suppose anybody can shed any light on that at all? I'm just curious is all and nobody seems to know what it means?

Well, apparently, you're a Sexually Transmitted Disease
but unfortunately I can shed no light on SUPN.

Ok so myself being an STD then means that i have a contract whereas if i was an SUPN it would mean that i have been drafted in as 'Extra help' having a time limit applied or something then???

This in mind. Would i be in a position to presume then that my job is relitavely safer once revision is in full swing at our place as opposed to being an SUPN? Sorry for the lamens term questions but i'm keen to know is all
