Is there a shortage somewhere? Here, when they had to hire a couple dozen teachers a few years ago )because of changes in the State Retirement plan that gave some an incentive to get out) 3,000 people applied for those 30 positions. Sounds like a glut to me.
At my kids school this year, when teachers quit they couldn't find teachers to replace them.
On reading the working conditions in your #235, I can understand why. ;-)
It depends on the field and the location. On the secondary level, I think social studies and English teachers are relatively easy to find, science, math, and foreign language teachers are more difficult, as are special education teachers.
