Lower-paid civil servants are to seek a flat rate increase in pay as part of forthcoming talks with the Government.
The Civil Public and Services Union (CPSU) said traditional percentage awards discriminated in favour of the higher-paid.
The union, which represents about 13,000 lower-paid staff in the civil service, has not put a figure on the flat rate increase it wants.
CPSU general secretary Eoin Ronayne said any sense of morality dictated that lower -paid workers should do best from any restoration of pay and conditions arising from the forthcoming talks.
