Postal workers from the Communication Workers Union have been striking in London since the beginning of June.
Postal workers in London have walked on on more than a dozen occasions in protest over pay and conditions.
The Communication Workers Union (CWU) says it is striking to defend future services as well as for jobs and modern conditions.
Royal Mail says it is only carrying out changes the union has agreed to.
The CWU is claiming there are 23 million items of mail backed up in London alone and says more national postal strikes could begin on Wednesday 28 October.
At the beginning of October members of the CWU voted by three-to-one to support strike action.

BBC London wants to build up a comprehensive picture of how the capital is being affected by the postal strikes.
Lesley emailed BBC London saying: "My passport was mailed via recorded delivery from Student Finance England from the 1st September 2009 and I have not received it up to this day. I have the tracking number but for some reason it cannot be traced/ tracked when entered on their track n trace system.
"Now, I'm being told that Student Finance has to fill out a P58 form (they being the sender) and submit it to them and God knows how much longer this will take before I know where on earth my passport is!"
Postal worker Stumps emailed in: "I work in a central London office and can tell you that after each strike day, our office is taking a minimum of three days to clear the backlog, (some walks four to five days).
Businessman Freddie Talberg puts striking post man Alan Smith on the spot.
We are told that we are not a public service anymore but a business and so its unrealistic for the customer to expect a reliable morning service.
"They have to get used to it!" I am told if I argue!
"We made £50 million profit on letters alone last tax year and over £300 million in other departments, as we see it, we can afford to provide a better service. The guys running the show just wont let us!
"No one in my office wants to strike, we have all been delivering to our customers for years and are ashamed and sorry for all the problems we are causing by taking industrial action but in the long run we are trying to protect their service as well as our jobs."
