In the region of 100,000 civil servants are geared to stage a 24-hour strike next month - as a bitter dispute over pay, jobs and working conditions is escalated to the next stage.
The Public and Commercial Services (PCS) union has today announced that members in 124 Government departments and other bodies are set to walk out on February 1.
The union also detailed that the action will come as the largest civil service strike in years, signalling a 'significant escalation' of industrial action following a month of strikes from members with the likes of Border Forces.
