The Royal Mail is considering closing its operation in Gloucester and moving it to Bristol.
It would mean the closure and sale of the Gloucester mail centre and the potential loss of jobs.
The plan follows five months of consultation with staff and trade unions.
Royal Mail is also proposing to create two mail processing units at the existing Gloucester North and Stroud delivery offices.
The organisation says its proposed change is in response to the challenges from digital communication, competition and mail volume decline.
A final decision will be made this autumn
