Strikes at the Scottish Qualifications Authority (SQA) will go ahead on Thursday, after a new pay offer failed to halt the industrial action.
Unite says up to 55,000 exam appeals could be affected by the strike, dismissing the revised average 7 per cent pay deal as a "cynical publicity stunt". The strike at the exams body will begin on September 8 and continue next week on September 15 and 16.
Union officials also announced six further dates for strike action in late September and early October, as well as an overtime ban. Earlier on Wednesday, SQA chief executive Fiona Robertson appeared at a Holyrood committee and told MSPs a new offer had been tabled.
