Are ALL airside employees (engineers, firefighters, refuellers, catering, Macas) subject to body scanning every time they enter their workplace?
What point would there be? For example, aircraft maintenance engineers need to purchase new tools from time to time and bring them airside (including trimming knives and other sharp implements). Staff also bring their lunch/dinner (large bottles/cans of drinks, food containers, etc) airside.... although there are random checks on MacDonald's takeaway bags
