A RAIL union has called for an "urgent" meeting with representatives to help solve the ongoing dispute with ScotRail bosses.

The RMT has written to five SNP MSPs from Glasgow, calling a letter signed by them "inflammatory, inaccurate and insulting" after they appear to have criticised the union for considering strike action during the COP26 summit.

General Secretary of the RMT, Mick Lynch, said he was "disappointed" about the language used in the letter after union members were accused of taking direction from "London bosses."

Mr Lynch confirmed in a letter seen by the Glasgow Times that this was not the case. The firebrand trade unionist, said: "I would also comment on the fact that your letter makes two separate references to “London bosses” and “London leadership”, implying that this was a deliberate decision and something you wished to emphasise.

"Choices over language are important and I think your decision to stress your mistaken view that decisions are being made by people from another country, was regrettable and leaves a bad taste in the mouth. It’s also insulting to the members and elected leadership in Scotland who are leading this dispute."

Mr Lynch called on the representatives to get round the table to solve the dispute, adding: "Where we do agree, however, is that it’s high time this dispute was resolved. I know that our reps in RMT Scotland are ready and willing to meet you at a time and place of your choosing to discuss how to resolve this long-running and unnecessary dispute.

"Instead of publishing ill-informed , inflammatory and insulting statements, I would invite you to meet with them to discuss how this can best be achieved."

This Sunday, Scotrail staff are set for further industrial action which has been ongoing for almost six months.

An SNP spokesperson said: “Our MSPs have huge respect for the RMT and the important role it plays on behalf of its members. We would also make the point that, whether politicians or railway staff, we are here to serve the public who pay for the railways and are the users of them.

“We would re-emphasise the point that the Scottish Government is not directly involved in this dispute, nor should it be. However, we fully accept that the Scottish Government is the major funder of the railways.

“We agree that language matters and we maintain our concern over the RMTs apparent willingness to undertake industrial action during  COP26. But we welcome their invitation to meet and hope this will be arranged in the near future. We will listen closely to RMT and hope they will listen to us, too, and realise the need to get to the table alongside Abellio to resolve this.”
