The unofficial postal strike in Oxford has ended after workers voted to return to work. More than 400 Royal Mail staff had gone on strike on 30 March over claims of bullying and harassment.
During the strike about five million items of post remained undelivered because of the walkout at the centre in Cowley and two delivery offices.
On Thursday afternoon staff voted to end their strike after a meeting between the unions and managers.

Staff are expected to take up their posts as normal at 2000 BST on Thursday.
Bob Cullen, from the Communication Workers Union, said: "They were unhappy to go back but they decided to take managers at their word.
"We believe that legally we were entitled to take action because it was a health and safety issue."
The backlog of letters is expected to take more than a week to clear.
The Royal Mail said it always took claims of bullying or harassment seriously and announced it had set up special "listening posts" for staff to voice concerns.
