A fast track ballot for strike action by Oxfordshire postal workers will open on Tuesday with the result being announced a week later.
The move follows the sacking of postmen Steven Gill and John Doran at the Oxford Mail Centre in Cowley for gross misconduct.
Communication Workers Union spokesman Sian Jones said: "The question being asked is 'Are you prepared to take strike action?' "Notice of any action and what form it will take will be decided upon when the vote comes in."
If a strike is announced, it will run separately from national strike action over pay and conditions, with an announcement about that due imminently.
The Royal Mail invited the CWU to come up with new proposals and return to the negotiating table.
