Post Office workers at more than 100 branches have walked out during a one-day strike in a dispute over pay.

       The 114 Crown Post Offices will close for a 24-hour period, with no cash deliveries or collections from the 11,500 sub-post offices around the UK.

       Members of the Communication Workers Union (CWU) are striking over a pay freeze for 2021 and the offer of a 2 per cent increase from April this year, alongside a ￡250 one-off lump sum.

       Union officials said the offer was “exceptionally poor”, especially as RPI inflation has reached 9 per cent.

       The dispute involves counter staff, as well as those in clerical, administration, and call centres.

       The Post Office said the vast majority of its 11,500 branches were not affected by the strike action and would be open as normal.

       Images posted on social media showed workers on the picket line outside closed Post Office branches across the UK, including in Glasgow, Belfast, north London, Derbyshire and County Durham.

       CWU official Andy Furey said: “Despite this union’s best attempts to avoid strike action, the Post Office has displayed no interest whatsoever in meaningful negotiations.

       “As such, workers have delivered an overwhelming mandate for strike action.

       “The current offer of a mere 2 per cent pay rise over two years is nothing short of an insult to these key workers who provided exemplary services to this nation during the pandemic.

       “As the cost-of-living crisis mounts, working people across the country are facing stark realities.

       “This isn’t any less true of Post Office employees, who deserve far better than the degrading offer currently on the table.

       “Post Office management need to understand that by undervaluing these workers, they have provoked real anger across the country.

       “We urge them to get round the table with us and reach a decent, fair agreement that shows respect for Britain’s key workers who kept post offices open for society during the pandemic.”

       A Post Office spokesperson said: “We want to assure our customers that the vast majority of our 11,500 branches are unaffected by this decision [to strike] and will remain open throughout the day.”
