SA Firefighter

Can some one explain to me why when we are all in the same service that there is so much brigade and group rivalry that they respond not just once or twice but constantly into others response areas without the courtesy of giving other briagdes a "call". I know of at least three instances in the last two days which are prime examples of brigades and groups responding well outside their normal areas (and not for specialist taskings either like road crash or tanker) but just a normal response. Quiet frankly I find this whole thing appauling that such rivalries get in the way of us offering a "proper" service that we all seem to think we belong to. We all blame "the establishment" for a lowering in morale of fire fighters, but I think that we need to look closer to home for a lowering of morale quiet frankly its a kick in the guts.
