I have spoken to a couple of schools this week regarding FI jobs, I started the course earlier in the year and hope to finish in the new year now, of the schools I spoke to, a couple where after full time instructors, and another had weekend vacancies for trial lessons, still a foot in the door though when a full time job becomes available.
There are still jobs out there and a couple of calls and/or visits to the school(s) you wish to work for will answer your question.
But things do seem to change quickly in this game!
