Eurostar passengers could face a week of disruption later this month after staff voted for strike action.
In a long-running dispute workers will strike over two weekends in August totalling seven days.
Four days from 0001 Hours on Friday 12th August 2016 until 2359 hours on Monday 15th August 2016.
Three days from 0001 hours on Saturday 27th August 2016 until 2359 hours on Monday 29th August 2016.
Eurostar said all passengers with reservations will be able to travel.
A spokesman said: "On the days of the strike we have made some small changes to our timetable to ensure that all passengers booked to travel will be able to on those days. Passengers affected will be notified in advance."
The RMT union said the dispute centres around Eurostar’s “failure to honour an agreement” from 2008 which sought to ensure that train managers could expect a good work-life balance in terms of unsocial hours and duty rosters - 95% of RMT members voted for action.
RMT general secretary Mick Cash said: "Our train manager members at Eurostar have a heavy commitment to shift work and unsocial hours and are sick and tired of the company's failure to honour agreements.
"Our members have every right to have a fair work-life balance that fulfils the operational needs of the company while guaranteeing quality time off for friends and family.
"It's now time for Eurostar to come to the negotiating table with a set of proposals that honours our agreements and guarantees our members a genuine work-life balance."
The action follows strikes on Southern rail and a looming dispute on Virgin East Coast after workers voted to walkout over a threat to jobs, working conditions and safety.
