The Fine Gael/Labour government is being warned it faces a similar fate to the Fianna Fáil/Green coalition unless it U-turns on the issue of special needs assistants (SNAs).
Campaigners opposed to reduced spending on SNAs are taking to the streets in Dublin later.
They will march from the Central Bank to the Dáil, demanding fair treatment for children with special needs.
Principal at Griffeen Valley Educate Together National School in Lucan, Co Dublin Tomás O'Dulaing said: "(The Government) can find money to bail out the richest and the most powerful in our society…but they can’t, they tell us, find the money to look after the most vulnerable in our society.
"We simply don’t accept that and will fight them until they change their minds."
The total number of special needs assistants is being cut from 10,800 to 10,500. Mr O'Dulaing said this equated to "300 children who are capable of great personal development, but who will be unable to attain that because of these cuts. It's the thin end of the wedge."
The protest march will begin at 3pm at Buswells Hotel on Molesworth Street.
