RMT general secretary Mick Lynch said: “This breakthrough has been achieved through the strength and determination of our members, whose industrial action has forced Avanti to engage seriously with this dispute.
Strikes planned by Avanti West Coast train managers over the next three Sundays have been suspended to allow negotiations in a long-running dispute over rest day working.
Members of the Rail, Maritime and Transport union (RMT) have already taken industrial action and were due to walk out again on the coming Sundays.
“However, Avanti must demonstrate a real willingness to compromise if it wants to avoid an escalation of this dispute in the coming weeks and months.”.
“We are fully committed to using the next three weeks productively to secure a negotiated settlement in good faith.
