I was reading in The Times today about the strength of the Lebanese guerrilla army, Hezbollah. The paper categorised the membership into "full time" and "part time", which I thought was an intriguing concept.
"What do you do, then?"
"Well, I've got a couple of part-time jobs. On Mondays and Tuesdays, I work at the pharmacy."
"So, what do you do for the rest of the week?"
"Oh, I fire a few Katyusha rockets and kidnap the odd soldier. Nothing much."
Very often, part-time jobs can be great way to get your foot in the door. If a full-time vacancy comes up - perhaps during a full-blown war with a neighbouring state - you'd be very well placed.
