I would have to agree, working for a ground handling company as a trainer myself. The biggest thing will be getting the necessary security clearance for Gate's new staff.
They may have the staff and equipment to handle such a large contract but it's not much good if none of the staff can get airside to do their jobs!!
Servisair have made the right decision by serving notice to ezy. At the end of the day the handling agent can't operate at a loss particularly in the current economic climate.
