Weekly strike action by ScotRail staff has been extended, with ticket examiners to walk out alongside their conductor colleagues this Sunday. This week was set to be the last of six Sundays of strikes by members of the RMT union, but instead the industrial action will continue. Earlier this month ticket examiners voted in support of walkouts, following a dispute over “equality and justice” surrounding extra pay for working rest days. This Sunday, May 2, will mark the first of six weeks of the ticket examiner's strikes. It was also due to be the last of six Sundays of strikes by conductors – who ScotRail claims are trying to force a 50% increase in overtime payments.
