A warning of flight delays and cancellations has been issued by easyJet after pilots operating for the budget carrier from Amsterdam confirmed strike action for tomorrow (Tuesday).

The walkout is part of a dispute over pay and pensions, according to the VNV union.  

The walkout is due to last from 6am to 2pm local time on Tuesday, with Dutch news agency ANP reporting that dozens of flights are expected to be affected.

The union argues pilots are expected to do too many flying hours for the salary they earn and only receive a fraction of their pay when they are sick, and that the company does not contribute enough to their pension fund, according to ANP.

An easyJet spokesman, confirming the industrial action, said: “We have been working closely with the VNV to negotiate a collective labour agreement.

“Although we have been unable to agree on some issues, we believe our latest offer represents a substantial improvement and we have already implemented a number of changes as a result of the discussions, as we know these issues are important to our pilots.

“We are disappointed at this unnecessary strike action and are working to minimise the impact to our customers. We’re sorry for any inconvenience this may cause.”
