Airports across Spain could come to a standstill in August after union leaders announced more than 60,000 baggage-handlers and other airport staff were prepared to strike.
The announcement comes after more than two years of failed negotiations over pay, working hours, breaks and overtime between the unions and airport authorities.
Labour mediation agency SIMA has now been brought in to try and broker a deal that both parties hope will alleviate the necessity to call a strike.
