The ASTI is to ballot its members on a set of pay proposals from the Department of Education.

The union's Central Executive Council took the decision at a meeting today.

It's recommending that members reject the proposals - which include a provision to opt-out of supervision and substitution duties and a gradual pay increase for newly qualified teachers.

The union will continue to defer its industrial action pending the outcome of the ballot, which will take place in January 2017.
