A final decision on the action will be made in a plenary meeting to be held on 26 December.
Employees of ground handling companies Groundforce and Portway and the union that represents them, Sitava, made the decision to hold a meeting to discuss possible strike action this week following a protest staged on Monday outside the National Civil Aviation Authority (ANAC)’s headquarters.
The workers accuse ANAC of conditioning the activity of assistance in airports.
Port and Airport Assistants might also join in the ground handlers’ action.
The Sitava union accuses ANAC of having “illegally licensed” Irish low-cost airline Ryanair and aviation recruitment agency Groundlink to provide assistance services on the ground in airports, which it claims was the cause of the collective firings in company Portway.
Union spokesperson Fernando Henriques said “We don’t know if in six months we will have a company to work for and the main person responsible for that is Luís Ribeiro [president of ANAC] so therefore we propose workers take up three days of strike.”
