I could see subbing, though I think in most parts of Canada I'm not qualified (my BA is in Classics--think Greco-Roman history--which isn't exactly a regular school subject). Similarly, I'd love to get into teaching future legal clerks and/or paralegals, which is typically not an onerous gig and with a much less, ahem, cutthroat student body than actual law school.
I feel like part-time retail could actually be quite fun if it's not what's paying the rent, but on the other hand, that would be pretty directly taking a job away from someone who needed it to, well, pay the rent. So might subbing, but probably not teaching paralegals (a job frequently done by a white-haired lawyer wearing a Rolex).
Mostly, though, I keep finding myself back at "fostering," which really can't be called a job in that it usually costs more than it "compensates," but talk about necessary, challenging, and potentially fulfilling. (Also potentially crushing, of course.)
