So If BAA Staff do strike; say Security and Fire Service is unmanned and the Airports are forced to close for a day. How secure are they going to be when they reopen? There are not enough Police to keep them secure during the strike; hence a massive security search would be needed before you could restart operations.
So perhaps the Government would have to step in to provide additional cover to allow the Airports involved to remain secure and possibly allow some limited service to continue.
I guess the RAF could supply enough Fire Crews and Vehicles to cover that side of things and maybe the Army would be able to supply enough troops to provide security. Although I don't think either the Police or Armed Forces would want to get involved with any of this right now.
Should be interesting!
