There's a lot of multi-tasking involved, Susan.
For example I spent today driving a parts van for a car dealership. But it's only casual work (although I've only had a few days without work so far this year), so I do other work as well. This evening I've been phoning all the contractors I'm currently supervising with the local distribution of Yellow Pages. (At other times of the year I work at a more senior level, supervising other team leaders as well as team leading contractors). I'm also considering working as a deliverer for the forthcoming distribution of the Thomson Local directory but I'm really hoping that some work will be coming up with the firm that I supervise traffic surveys for.
There's been plenty of multi-tasking in the past as well. While I was working, on a 'commission only' basis, as a rates advisor I supplemented my income by working behind the bar of one pub on Sundays, while working as weekend bar manager in another on Friday and Saturday nights and managing a local sports club bar during the rest of my (so-called) free time.
When I was still at school I started writing sports reports for the local rag. They were initially unpaid but I started getting a few quid after a while. Since then I've done quite a bit of writing (and made some money from it), mainly for magazines and technical journals. However it's always been 'part time' in addition to whatever else I've been doing at the time, so it's yet another example of 'multi-tasking'.
At various other times I've dabbled in the antiques trade (by buying items at auction and then selling them through a friend who sold at antiques fairs), worked as a relief presenter for BBC local radio and several other things.
However my 'full-time' c.v. basically includes teaching, will drafting, 'trade plating' (delivering vehicles to auction) and running a railway station. Everything else is an 'add on'.
