Around 1,500 members will join the one-day strike and normal services will resume on Tuesday 12 July.
The union said the offer was “horribly inadequate” and well below inflation, which stood at 9.1 percent in June.
Andy Fury, CWU assistant secretary, said: “No worker wants to be in this situation, but post office bosses can’t be surprised that our members are challenging the callous decisions.
“This dispute is about the dignity and respect of hard-working employees, essential public servants who, as key workers, have provided unprecedented customer service during the pandemic.”
