Staff at a Post Office in Kings Heath will walk out in protest over jobs, pay and closures today.
Commercial Workers Union members will be protesting outside the branch as it is one of 70 that could be closed or turned into a franchise.
300 Crown Post Office staff members, from across the UK, are expected to walk out in support of the protest.
The Post Office say that nearly 12,000 branches are unaffected.
The Communication Workers Union (CWU) claims that plans to close or franchise 70 of the UK’s biggest post offices - known as the Crown network - will affect hundreds of jobs.
Dave Ward, the CWU's deputy general secretary, said, "Our Post Office members are standing up against destructive plans which would slash 20% of the Crown network and are simply asking for fair treatment and job security.
"The Post Office's plans are short-sighted and would rob the network of the most productive offices while simultaneously putting hundreds of jobs at risk and potentially damaging local economies.
“We'd like to see a better vision for a successful network which maintains services in the heart of communities alongside quality jobs.
"We're confident this could be achieved if Post Office management would agree to negotiations".
Residents in Stoke-on-Trent are being forced to travel three miles to collect their post because uneven slabs outside their homes are considered a safety risk. The Royal Mail has suspended deliveries to two roads in Penkhull after raising concerns.
And homeowners are being told because they own the paths they must pay for repairs.
