Pre-Christmas strikes for security staff on Eurostar. Strikes are to take place on 16, 18, 22 and 23 December
Eurostar security staff to strike in run-up to Christmas
Members of the Rail, Maritime and Transport (RMT) union, employed by a private contractor, voted overwhelmingly in favour of the action.
Eurostar said it would update customers as soon as possible if there was any impact on services.
However, the union said the strike would "severely affect" passengers.
More than 100 security staff employed by facilities management company Mitie are due to walk out, following a 4-1 vote in favour of strike action.
