Eurotunnel said it had reached an agreement with trade unions and apologised for disruption to LeShuttle, which transports vehicles through the Channel Tunnel.
“Eurotunnel management and trade union representatives have reached an agreement at the end of a day of strike action which led to the interruption of services,” it said.
“This agreement means that LeShuttle services have now restarted. Incidents of this nature are extremely rare.”
It added it would not be selling new tickets for travel on Friday. Instead, it will focus on those who have already have tickets.
