SCHOOL leaders across Wales have overwhelmingly voted to take further industrial action, NAHT Cymru announced today.

The headteachers’ union said that 95 per cent of those balloted this month supported continuing action short of a strike and about three-quarters endorsed walkouts. 

The latest six-month mandate comes after the workforce voted in March to reject an improved but still below-inflation offer from devolved Labour ministers of 3 per cent in this academic year and a further 5 per cent in September.
