The swanky new Caledonian Scottish Sleeper could be facing a staffing crisis after union members voted overwhelmingly for industrial action.

The service, run by SERCO, is currently at loggerheads with workers over what union bosses are calling "intolerable pressure on staff"following the introduction of new fleet.

The RMT say its members have had to deal with insufficient staffing levels and training, as well as an unresponsive management regime, leading to workplace stress and mental health issues.

The problems sparked a ballot, with members voting ten to one in favour of both strike action and action short of a strike.

The result will now be considered by the union’s executive who will decide on the next steps.

In a statement, general secretary of the union Mick Cash said: “Our members on the Caledonian Sleeper are sick and tired of paying the personal price for the botched introduction of the new fleet and that is why they have delivered this overwhelming vote for action.

“It is time for SERCO to wake up and take note of the appalling working conditions their mismanagement has lumped on their staff and to take action to resolve this dispute.

“The result will now be considered by the union’s executive and we remain available for genuine and meaningful talks.”

Ryan Flaherty, Serco’s Managing Director for Caledonian Sleeper, said: “We’re deeply disappointed by the result of the ballot.

"I believe we have shown a real commitment to dealing with the issues the RMT has raised and indeed there was an acceptance on all sides that progress was being made.

"We remain open and willing to engage in further talks to avoid industrial action and are fully committed to delivering the best possible service to guests.”
