The result is that this country's local governments are spending much less on education than they were a few years ago, and therefore employ many fewer teachers. Because they have a mandate to educate basically the same number of children as before the crisis, this means larger class sizes, etc.
To suggest that these unemployed teachers are 'surplus' in this environment is to mis-characterize the situation almost to the point of dishonesty.
If they reduced the compensation of teachers (i.e., reduce price in response to a demand decrease), there would be no need to reduce the number of teachers.
Of course there is - the quantity demanded at a fixed price is set to go down by (according to the DoE) 280,000. I.e., the demand curve has shifted left.
