The next round of postal strikes was cancelled on Thursday night as the CWU reached a deal with Royal Mail.
Action was planned for Friday and Monday but staff returned to work after an eleventh hour agreement was reached.
The announcement has met with approval from postal workers, some of whom have heavily criticised the strike.
The agreement includes a two month “period of calm” while Royal Mail bosses review proposed changes to the way employees work.
Other measures include a negotiation of the local issues which led to the initial strike and a promise that postal workers will be able to work normally and “have the chance to earn more money” over Christmas.
CWU deputy general secretary Dave Ward said he was very happy with the agreement.
“We can now have a period of calm where we hope we can genuinely take forward modernisation in a way that puts the union at the centre,” he said.
“Our members will now know we can deal with modernisation in a way that gives them improved job security and improved terms and conditions.”
Postal workers welcomed the announcement. One local Royal Mail employee, who asked not to be named, said that many see strike action as a waste of time.
“Most of the lads at the local office are sick of striking; we’ve done it before and we never achieve anything” he said.
“The majority I’ve spoken to are just relieved that they’re not losing any more money.”
“The only reason this agreement has happened is that Royal Mail know they have messed up by bringing in temporary workers during the strike.”
But Edinburgh CWU representative Willie Marshall played down the apparent rift between union members and leaders.
“The trade union exists to protect their terms and conditions, they were under attack and the post office weren’t backing down,” he said.
“There were lots of local issues across the country which could only be dealt with through national action. No one else is able to stand up to the company for them.”
This announcement puts an end to fears that a strike would cause problems over Christmas.
