Charts: Too Many Education Types, Not Enough Education Jobs
This handy dandy EPI chart shows that there are many more workers than job openings across a bunch sectors including education (and health).
It's not as bad as in wholesale and retail trade, or even in leisure and hospitality, but it's not very good, either.
Again, education sector unemployment seems to have hit classroom aides and paras and other noncertified staff (preschool teachers?) as much or more than classroom teachers.
