Hundreds of Putney residents and businesses are still waiting for their mail to arrive - two weeks after the postal strike finished.

They said postmen were not completing rounds because of a backlog of parcels and letters which built up during last month's strike over pensions and pay.

Jonathan Callaway, of Luttrell Avenue, said: "My postman told me there is still a big backlog at Nine Elms (the sorting office) that hasn't even made it to the Putney office yet. I'm still waiting for some bills, which I can't pay until I receive them."

Allen Bracchi, a conference producer from Kersfield Road, said he had just received employment contracts a month after they were posted.

He said: "Some days I have got nothing, others it comes really early. It's really inconsistent.

A member of the Communication Workers' Union in Wandsworth, who did not want to be named, said up until last Friday there had been no paid overtime. "There is a massive backlog. Management are refusing to put extra time on to clear the backlog, because they say that will compensate the postmen who took industrial action."

Nicky Carter, area delivery representative for the CWU, said: "At Putney, they are offering some overtime, but not enough. Their view is that they are not going to pay us overtime because we went on strike. They should be offering resources to clear the backlog."

Royal Mail said it was offering overtime to staff at the Putney delivery office. A spokesman said: "We are working hard to clear backlogs of mail resulting from industrial action taken by CWU members. This includes our Putney delivery office, where additional overtime has been made available to ensure all mail is delivered as soon as possible."

Putney MP Justine Greening said: "There is obviously conflicting communication from management and the unions. It sounds like everyone needs to get together and discuss how they are going to clear the backlog."

She has asked for an urgent statement from John Hutton, Secretary of State for Business, and added: "I have had dozens of emails from my constituents about this. There has now been a month of disrupted post.

"There are businesses waiting for invoices and payments and valuable items still in the post, and I am concerned that I am not receiving my letters."
