Tensions as threat of mass UK strike looms large
Ministers have clashed with union chiefs over claims next week's public sector strikes could cost the UK £500m and lead to job losses.
Downing Street has stood by the claim, saying it is a "fact" that closed schools will stop many parents going to work, which has an impact on "output".
But unions have accused them of scaremongering and "fantasy economics".
More than two million workers are expected to join action on 30 November over changes to public sector pensions.
