Staff at Tendring Technology College began a three day strike this morning (25th May) over plans for a restructure which they say will cut teaching and support roles from September.
They were joined on the picket line at their two sites in Frinton and Thorpe-le-Soken by parents and students who feel strongly that Academies Enterprise Trust should relinquish control of the school.
The Trust told ITV News Anglia that it was "deeply disappointing" that unions called members out to strike after "all the students have had to contend with", in the last year.
Two more days of strikes are planned this week, with pupils once again being taught online.
Both sides have agreed to resume talks as soon as possible but the National Education Union is making it clear that AET needs to be willing to have meaningful negotiations to resolve this dispute.
The Trust says it has "engaged with ACAS to seek further talks with the unions to try and re-engage on the issues."
The Trust says it will continue to keep parents updated on any developments and will be providing online learning for students to minimise any further disruption.
