Royal Mail workers are to stage 19 strikes in October and November as a continuing dispute over pay and conditions continues.
The Communication Workers Union announced that the action over the next two months will be a mixture of single days and rolling action across the network of the Royal Mail Group. The union expects it to have a "dramatic impact," with the industrial action covering peak mail periods such as Black Friday, Cyber Monday and the Christmas build-up.
Royal Mail workers took four days of industrial action in August and September with more than 100,000 workers taking part, making it the biggest strike of those which took place over the summer. However, the action announced on Tuesday night could be even bigger, with cleaners and engineers also voting to strike over pay.
