May 12 and 13 will see workers employed by Train Operating Companies (TOCs) on the mainline railway return to industrial action after a lengthy pause. RMT members, who strike on the 13th, returned a huge majority for action, on a 70% turnout, in their latest re-ballot. Drivers’ union Aslef has also rejected the latest offer put to it by the Rail Delivery Group, the umbrella body representing the TOCs. Aslef drivers strike on the 12th.
