Royal Mail workers are to stage a further 19 strikes in the next two months in a deteriorating dispute over pay and conditions.
The Communication Workers Union announced the action in October and November will be a mixture of single days and rolling action across Royal Mail Group's network. The union said it will have a "dramatic impact" and will cover peak mail periods such as Black Friday, Cyber Monday and the Christmas build-up.
The union said the move follows a threat centred around the "outrageous" decision by Royal Mail Group's senior management to withdraw from major national agreements, push ahead with cuts to workers' terms and conditions and "completely sideline" the union.
