Belfast city centre has seen angry demonstrations from hundreds of Royal Mail workers as they went on strike over issues with their management.
Postal deliveries in the north, south and west of the city have been disrupted with no mail being processed.
The strike action was started by over 200 postal workers at the city’s Tomb Street depot and concerned accusations of bullying by the staff management.
However, Ray Ellis a national Communication Workers Union (CWU) representative told the strikers that their actions were unofficial and that they should return to work.
Mr Ellis said: “If they continue to refuse to talk, then I’m afraid our members are going to face more loss of money and customers are going to face more disruption.”
Royal Mail have maintained that any discussions will only occur once workers have left their picket lines but staff say they will not return to work until the original dispute is resolved.
