A general strike in Spain is likely to cause travel disruption to and from the country this week.

Spanish trade unions are to stage protests against the government’s austerity cuts and labour reforms on Wednesday.

They are reported to have agreed with the government to provide a minimum of between 20% and 40% of international flights.

The protest will leave at least 20% of European flights and 40% of other international flights unaffected.

At least one quarter of train services would run, rising to 30% at rush hour. Under Spanish law, workers in certain sectors must provide a minimum level of services and the unions must agree with the government on what minimum levels should be.

The scale of transport stoppages is likely to be a key factor in the level of disruption caused by the strike as they determine how many non-strikers can get to their place of work.

Significant disruption in large cities is expected.
