ACT public schools will close for a full day on 11 June as teachers prepare for a second round of industrial action in an ongoing dispute over pay, working conditions and school resources.

Education Directorate Director-General Jo Wood confirmed the closure, stating that a majority of teachers are expected to participate in the strike, making it impossible to guarantee safe and appropriate supervision of students.The decision follows an earlier strike on 22 May, when schools were closed until 10.30am during a two-hour work stoppage, the first teacher strike in the ACT in 15 years.

The Australian Education Union says its members are taking action because negotiations with the ACT Government have continued for 11 months without a formal offer being presented.Union representatives argue that educators are seeking improved conditions, additional resources and fairer pay.

Union president Angela Burroughs criticised the government's handling of negotiations, rejecting claims that the bargaining process is unusually complex.Teachers participating in the previous strike reported that insufficient resources are affecting students and classroom outcomes.Education Minister Yvette Berry said discussions with the union will continue in an effort to reach a positive resolution.

Meanwhile, members of the ACT Legislative Assembly have called on the minister to address the union's outstanding claims and provide an update on progress before the planned strike.

Families may face disruptions due to the school closure, while arrangements for out-of-school-hours care and student assessments will be determined by individual providers and schools.
