The airport security union representing workers at Brussels South Charleroi Airport signed an agreement with the Wallonian regional government which guarantees a minimum level of service in the event of future strikes, according to Belgian weekend press reports.
The agreement guarantees that, in the event of a grievance, all other avenues of dialogue will be exploited before a strike is called, according to Belgian financial daily L'Echo.
According to La Libre Belgique, the text states its aim as 'guaranteeing social harmony' at the airport.
The agreement comes following reports last week that Irish low-cost carrier Ryanair was to suspend flights from the airport from November following a series of 'wildcat' strikes.
The airline told La Libre Belgique that it was satisfied with the agreement and would resume the sale of flights from today.
