More than 115,000 Royal Mail postal workers are set to strike for four days over the next four weeks.
Staff who are members of the Communication Workers Union (CWU) say the industrial action will be the biggest strike of the summer so far. They are calling for a no-strings "dignified, proper pay rise" in the wake of soaring inflation. The Bank of England expects inflation to hit 13% in the autumn.
Royal Mail argues that it has given an unconditional 2% pay rise, backdated to April and has offered a further 3.5% increase (totaling 5.5%), subject to staff agreeing to targets and a series of changes to their conditions. The CWU call for a 'no-strings' pay rise, but Royal Mail says changes are essential if it is to keep up with rival logistics companies.
