Is that my job?

Every day I get asked to do a wide variety of stuff, some of which is very clearly a part of my job, but some of which really isn't. So, I present:

Stuff that's my job

• Preparing equipment for practical physics lessons and ensuring that it's in the right room at the right time.
• Repairing any bits of equipment which get broken. (Mainly changing batteries and fuses, sometimes a bit of soldering)
• Sourcing new equipment and dealing with ordering.
• Managing the budget
• Trialling new experiments eg ISA practicals
• Helping out in the lab during practicals
• Demoing experiments during lessons
• First Aid

Stuff that's not my job, but which I still get asked to do

• Booking plane tickets
• Invigilating exams when they can't find anyone else
• Contacting kids' parents
• Entering exam results onto the system
• Photocopying
• Setting work when a teacher is away but hasn't sorted out any cover
• Taking phone messages from my HoD's wife

And today's prize example - find out where the course is which my HoD is supposed to be on. Seiously, he called me at 9.15 to ask me to log on to his e-mails and check the venue for his course because he'd forgotten to write it down. Sometimes I despair.
