The problem of a workforce and management at loggerheads is simply unforgivable in an age of huge amounts of management training - MBA courses and the like - none of which would advocate this course of action. Perhaps BA are not recruiting enough fresh, young MBAs, and still have too many old codgers from the times of the nationalised business.
An understandable assumption but with the exception of the lower echelons of flight technical and flight training management who are universally respected the vast majority of BA management are not from the nationalised era but do endeavour to be seen as though they are.
