Not really. I’m no fan of the RMT but they settled for an offer marginally higher than what they were originally offered and lower than what they originally wanted.
It’s basically the same deal that the other unions accepted. The SNP, who run rail in Scotland, have never had a pay freeze in place. Abellio, the TOC, don’t give a stuff as they’re exiting and the money from this comes from Holyrood, not them.
