A secondary teachers union has accused the Education Minister of opening talks on a second Croke Park deal through the media.

It comes after Ruairí Quinn told the Sunday Times he wants negotiations for a second agreement to begin in the Autumn.

The deal protects pay levels and increments and does not allow compulsory redundancies.

It has been criticised by among others the Transport Minister Leo Varadkar.

Diarmuid de Paor is General-Secretary the Association of Secondary Teachers in Ireland (ASTI).

Speaking to Breakfast here on Newstalk he said teachers have given up enough already.
