The Portuguese Airline Pilots’ Association (SPAC) has announced a 10-day strike in protest over TAP’s ongoing privatisation process.
In a statement on its website TAP said the strike, which is planned to take place from May 1, will “strongly affect” its operation and that it “will do everything in its power” to ensure that the strike does not go ahead.
In January, the Portuguese government said it planned to sell 66 per cent of the airline, with the remaining shares to be sold off two years after the privatisation is completed.
The government also put a 30-month ban on staff redundancies for future owners of the airline.
TAP has around €1bn ($1.1bn) in debts and the Portuguese government is banned from loaning any more money to the airline under EU rules.
