Postal workers throughout the North were back at work today after the withdrawal of loyalist death threats made following the murder of postman Daniel McColgan.
Royal Mail said they were pulling out all the stops and "doing all we can to clear the backlog and get service back to normal".
Workers in Derry were the last to vote today to return to work, following a similar decision by their Belfast colleagues yesterday.
Consignia said they had still not decided whether to reopen the delivery centre in the heart of the loyalist Rathcoole Estate on the northern outskirts of Belfast outside which Catholic Mr McColgan was shot dead as he arrived for work on Saturday.
All staff and equipment have been temporarily moved to the main Royal Mail sorting office a few miles away at Mallusk, Co Antrim.
Meanwhile preparations continued today for rallies tomorrow protesting against the murder and threats to postal workers and teachers.
Tens of thousands of workers are expected to attend the rallies organised in Belfast, Derry, Enniskillen and Omagh by the Irish Congress of Trades Unions.
The ICTU has urged political groups not to try and hijack the rallies.
Regional organiser Mr Tom Gillen said he was conscious of groups who may try to use the protest to their own advantage but he wanted to make it clear to workers everywhere: "This is a non-political, non-sectarian demonstration. This protest is about the whole community."
In a blunt message to political extremists he said: "Stay away. You are not wanted."
Northern Ireland Secretary Dr John Reid has urged workers to join the protests. He said there was a need for an "extraordinary unity of purpose" following the murder of Mr McColgan.
Large sections of business and industry are expected to come to a standstill for the rallies, though many employers, while facilitating attendance at the midday gatherings, have urged their workers not to take part in the full noon to midnight stoppage called by the ICTU.
Rail services across Northern Ireland will be halted for two hours and disrupted for at least an hour either side and bus services hit. Curtailed services will be provided to get people away from the rally points after the protests.
Earlier a statement was issued by the Red Hand Defenders saying they had lifted death threats against teachers and postal workers after meeting unionist politicians.
"All death threats to Catholic postal workers and teachers have been lifted indefinitely," the statement said.
The Red Hand Defenders made the move after the UFF condemned the threats. However the two groups are believed to be one and the same.
