Thousands of Post Office staff at more than 100 branches will strike next month in a long-running dispute over pay.
Members of the Communication Workers Union (CWU) who work at 114 Crown Post Offices - those run directly by the Post Office - will walk out on July 11.
The union has rejected a pay offer it said was worth 3%, on top of a freeze from April 2021, and a £500 lump sum.
It called the offer "insulting" as prices rise as their fastest rate in 40 years. Inflation, in comparison, has just hit 9.1%.
The Post Office said the vast majority of its 11,500 branches would be unaffected by the strike action.
"There are 114 branches, typically in city centres, that are directly managed by Post Office and on previous strike days over a third have opened as usual," a spokesman said.
"We’re disappointed that the CWU have made the decision to strike but remain hopeful that we can reach a pay agreement soon."
The pay row involves counter staff, as well as those in clerical, administration and call centres.
A spokesperson from the Post Office told The Mirror around 1,500 workers are expected to take part in the strike action on July 11.
Around 3,500 members of staff are thought to be involved in the dispute altogether.
CWU assistant secretary Andy Furey said: "No worker wants to be in this situation, but Post Office bosses can't be surprised that callous decisions are challenged by our members.
"Our members feel betrayed and will not tolerate their living standards being smashed by people in charge of a public service that due to our members' efforts made tens of millions of pounds in annual profits."
It is the third day of strike action by Post Office workers so far this year, with industrial action last taking place in May.
Separately, more than 115,000 Royal Mail workers will today begin voting on whether to go on strike over pay.
Ballot papers are being dispatched to CWU members from today, with the result on 19 July.
Royal Mail said it believed there were "no grounds for industrial action".
"We offered a deal worth up to 5.5% for CWU grade colleagues, the biggest increase we have offered for many years, which was rejected by the CWU," a spokesman said.
"We need to reach an agreement on the changes required to ensure Royal Mail can grow and remain competitive in a fast-moving industry, securing jobs for the future and retaining our place as the industry leader on pay and terms and conditions."
Further talks between the Royal Mail and CWU are scheduled this week.
