Post Office staff have voted overwhelmingly for strike action following planned cuts to jobs, services and staff pensions.
Members of the Communication Workers Union (CWU) who took part in a ballot backed industrial action with 83.2% in favour.
The union warned the Post Office is on the "path to extinction" and said the government must intervene to avoid strike action.
General secretary of the CWU, Dave Ward, said “staff in the Post Office face 2,000 job losses this year, the closure of their pension scheme and a strategy of slash and burn from the board of the company.
"The Post Office is at crisis point and the government has to step in.
"It cannot wash its hands of this and simply stand by as a national institution goes under."
