blockade/protest in front of the Fianza office

My Spanish continues to fail me, or I to fail it, but it appears it has something to do with teachers protesting the replacement of a school official.

I welcome correction.

Or it has to do with non-payment of correct wages for special eduction teachers?

The second link says the teachers are looking for ”concrete solutions”. Shouldn’t the mayor be able to help with that?
