Northern has responded to RMT's announcement of further strike action on 19, 21 and 23 June (Tuesday, Thursday and Saturday).
Richard Allan, Northern’s Deputy Manager Director, said: “Northern is working extremely hard to stabilise and provide certainty in delivering a reliable train service on those parts of our network affected by recent very significant disruption and cancellations.
“We have apologised repeatedly and extensively to customers, are working urgently on our additional customer compensation offer, and our energy and focus is on providing a better service for customers.
“The May timetable problems and the latest RMT strike action will not deter us from delivering our modernisation plans for customers - £500m of new trains which are currently under construction, better stations and more services by 2020.
“We are still prepared to guarantee jobs and pay reviews for conductors until the end of our franchise in 2025, with the Government guaranteeing jobs beyond that, but both guarantees depend on RMT ending its strike action.”
