LONDON (Reuters) – An attempt by school teachers belonging to the NASUWT trade union in England and Wales to carry out strikes over pay failed as the turnout of voters in a ballot fell short of the required level. Nine out of 10 members of the NASUWT union voted in favour of striking but the turnout was only 42%, the group said in a statement. That is below the legally required 50%.
