HUNDREDS more ScotRail workers could be headed for strike action as the Scottish government-owned company fails to table a “credible” pay offer.

Unite the union will ballot more than 300 train cleaners, engineers, ticket agents, hospitality assistants and conductors for strike action from Wednesday, joining comrades in Aslef and RMT whose ballots are underway.

In line with SNP Scottish government public-sector pay policy, the operator offered workers a sub-inflation 2 per cent pay uplift backdated to April, followed by 1 per cent in January, in a pattern to be repeated in each of the following two years, but roundly rejected by all unions at ScotRail.
