**Passengers hoping to cross the Channel by ferry are facing further disruption as a strike by SeaFrance workers in Calais enters its second day.**The 48-hour strike by CFDT union members led to the cancellation of all SeaFrance crossings from Dover to Calais on Friday.
The company said further cancellations may be necessary on Saturday.
It said it was advising passengers not to travel to Dover unless they had a booking with another operator.
A message on the company’s website said: "The company profusely apologises to customers affected. The advice is that unless and until you have a booking with another operator you should not travel to Dover.
“The port is extremely busy and it will not be possible to transfer you to another operator on arrival.”
‘Very regrettable’
The French workers walked out in protest at new working practices.
Operation Stack - where lorries waiting to cross the Channel park on the M20 in Kent - was put in place throughout the day on Friday as traffic built up around the port.
On Friday, SeaFrance managing director Robin Wilkins described the walk out as a “very regrettable decision” and said it had come at one of the busiest times of the year for the port.
Kent Police said Operation Stack would be restarted if traffic around the port returned to high levels on Saturday.
The force said the Port of Dover was “still busy” on Saturday night.
In a statement it said: "People are still being advised to check with their travel operator before starting their Easter journey.
“Operation Stack is only introduced as an emergency measure after consultation with other agencies and implemented following a thorough assessment of issues, including safety concerns and disruption on the road network.”
The Port of Dover warned passengers not travelling with SeaFrance that they may need to leave extra time for their journey because of the strike.
A statement on the port website said: “Please bear with us as we endeavour to process port traffic as quickly and safely as possible.”
SeaFrance said it was updating customers about cancellations through texts, e-mails and messages on its website.This article is from the BBC News website. © British Broadcasting Corporation, The BBC is not responsible for the content of external internet sites.
