Royal Mail staff across the country will walk out on two more dates this month in a row over pay and conditions.
It is the latest in a series of walk-outs which were confirmed by the Communication Workers Union (CWU) last month.
A strike on Thursday (October 13), was the first of 19 dates set for industrial action throughout October and November, with further dates planned for December to cause disruption during the Christmas period.

The CWU said 115,000 of their members will be taking industrial action, making the strike one of the largest this year. Royal Mail has apologised to customers, and says people can expect "significant disruption".
It added: " Royal Mail has well-developed contingency plans, but we cannot fully replace the daily efforts of our frontline workforce. We’ll be doing what we can to keep services running, but we are sorry this planned strike action is likely to cause you some disruption.
"We have been able to recover services quickly after recent CWU strike action and we will continue to focus our efforts on working to get our services back to normal as soon as possible after any future strike action.
Workers are set to strike on:
- Thursday, October 20
- Tuesday, October 25
On strike days, Royal Mail said it will:
- deliver as many Special Delivery and Tracked24 parcels as possible
- prioritise the delivery of covid test kits and medical prescriptions wherever possible
- not be delivering letters (with the exception of Special Delivery)
It is also advising customers to:
- post items as early as possible in advance of the strike dates
- continue to post items at Postboxes or Post Offices, however collections will be less frequent on days when strike action is taking place
