The looming national rail strike could cost the economy more than £90million.
The RMT has confirmed plans for three days of walkouts by tens of thousands of rail workers on June 21, 23 and 25 in a dispute over pay and half that £90m hit to the economy is estimated to come in the first day.
It comes amid what is threatening to turn into a “summer of discontent” as hundreds of thousands of workers across a raft of sectors gear up for possible industrial acton.
