"We have reached the limits of human endurance, we are in no fit condition to maintain this service, which is of great importance to this country, given the way we are managed and treated. WE HAVE NO CONFIDENCE IN OUR EQUIPMENT, OR IN THOSE WHO MANAGE US! We are working with rifles pointed at us.." This is how the air traffic controllers of Brasilia, Curitiba, Manaos and Salvador, dramatically expressed themselves in a Manifesto, before paralysing the services from midday Friday 30 March, by calling a hunger strike and shutting themselves into their workplaces, in order to put pressure on the Aeronautical Command, the military organ responsible for air traffic control in Brazil.
