Postal workers in Oxfordshire are to hold a one-day strike.

Members of the Communication Workers Union (CWU) will stage a walkout on November 4 after backing industrial action by 78 per cent over concerns about the privatisation of the service.

The union said it will consider further action and announced an escalation, with a new ballot which will enable postal workers to boycott competitors' mail.

CWU deputy general secretary Dave Ward said: "Postal workers have spoken very clearly that they care about their jobs, terms and conditions far more than they care about shares."
