Caledonian Sleeper workers will take strike action for 11 days later this month over a pay dispute.  

The Rail, Maritime and Transport (RMT) union held a ballot claiming service operators Serco "attempted to impose a pay freeze on hardworking staff who have kept the service running throughout the COVID pandemic."  

All staff grades were involved in the ballot, which returned an 85 percent vote last week in favour of a strike.  

The union has now confirmed the strike will take place from 11:59 a.m. on Tuesday June 15 to 11:59 a.m. on Saturday June 26.
