Empty bottles, cans and trash are piling up at Madrid's airport as cleaners enter the fifth day of a strike to protest proposed layoffs.

The strike continues to affect terminals 1, 2 and 3 on Tuesday, a day after a similar strike at Terminal 4, the airport's main terminal, was suspended after one day.

The strike is made worse by the fact that the airport has very few trash containers for the public to use.

The cleaners are protesting plans by their cleaning company to lay off 54 out of 270 workers at the airport.
