Staff at the Scottish Agricultural College have voted to take industrial action next month. Some 84 per cent of members of trade union Prospect backed the move; the turnout was 75 per cent.
Union negotiator Alan Denney said: "This result sends a clear message to management that staff will not accept a deal that amounts to a zero pay increase for over 80 per cent of staff."
A college spokesperson said: "SAC will continue to work with the union to seek a solution." The college has sites in Aberdeen, Ayr and Edinburgh.
