But not all industrial action was averted in Italy. More than 200 flights were cancelled and many others delayed when air traffic controllers went on strike for improved contracts.The stoppage affected hundreds of domestic and international travellers in Rome and Milan. It was the second air traffic controllers strike this month. Italy’s air traffic controllers’ authorities are disputing the interpretation of contracts signed last year. The debate centres on issues including working hours and benefits. The unions are threatening more stoppages on June 6 and June 8. Alitalia pilots are planning to strike on June 26.
