Unions representing teachers, community education workers and support staff in Glasgow have been told to expect 550 redundancies in the city's education department. Official 90-day redundancy notices have been sent to the unions.
A council spokesman said heads of departments had been asked to restrict losses to early retirements and voluntary redundancies.
The Educational Institute of Scotland met city MPs on Tuesday and warned that a forecast 6 per cent cut in the education budget would mean increased class sizes, no support for children with learning difficulties, lack of subject choice in secondaries, problems providing Higher Still, possible part-time education, and one in nine teachers being made redundant.
Gill Mackay, who chairs the EIS in Glasgow, said: "The disruption and damage to children's education could be enormous." More than 50 schools are facing disruption in the new term because of emergency staff transfers at Christmas.
EIS members in the city will hear calls for ballots on industrial action at a meeting next Wednesday.
