“DONE-IN” teachers could consider strikes if the Scottish government and councils do not agree to a ban on classes with more than 20 pupils, the Education Institute of Scotland (EIS) warned today.

Delegates at the teaching union’s annual general meeting overwhelmingly voted to launch a “20:20 Vision” campaign. It demands a reduction of the maximum class size from 33 to 20 and of contact time from 22.25 hours a week to 20.

EIS council member Andrew Fullwood told delegates that the demand was “the next step in the Value Education, Value Teachers campaign,” through which Scottish teachers recently won a substantial pay rise after preparing for a strike ballot.
