Britain is "heading in the direction" of mass industrial action akin to a general strike, a trade union boss has warned.
Mick Whelan, head of train drivers union Aslef, vowed that workers would "keep fighting" until they get better pay and suggested strikes could be coordinated on a mass scale in the future.
Speaking after Aslef announced fresh strike action in January, he said he was “sorry” for the disruption to passengers but added: "Unless we have an impact, how do we change things?"
