Iberia workers to hold five-day strike "It will be at least five consecutive days, but the date hasn't been set yet, it will be in the second half of February," he said. Unions representing Iberia's ground and cabin crews rejected a fresh proposal by management on job and salary cuts on Thursday, before a deadline for agreement, and said they planned to strike. The International Airlines Group, comprising British Airways and loss-making Iberia, had offered to reduce job cuts at the Spanish airline by 30pc to 3,147 and lower wage reductions. Iberia, which has suffered periodic strikes since it announced the creation of budget arm Iberia express, has estimated it loses €1m (£860,000) for every day crew strike.
