Controllers at CANAC manage and ensure the safety of airplanes flying over and approaching the airport up to an altitude of 7,500 metres. The Belgian and Luxembourg airspace monitored from this centre is divided into portions and, because of the shortage of staff, one of these, Sector East, will simply be closed from 1:30 a.m. to 4:00 a.m on Thursday, Dehaene said. As a result, no planes will be authorised to land at Liège, the main airport affected.
Workers and management at Skeyes have been locked in negotiations on a series of demands: the Christian federation, Confédération des syndicats chrétiens de Belgique (CSC-ACV), listed 23 demands, some of them longstanding, in its strike notice, which covers actions up to 23 March.
On Tuesday night even more workers had been off the job in response to a call by CSC-AVC and the public service union, Syndicat libre de la function publique (SLFP)
Management has invited the unions to a meeting to be held on Thursday at 2:00 p.m.
