BA have in the past sent staff on courses for corporate spirit building - I can not confirm that this included fight crew but it is a fact for many others in administrative roles.
The point is though ( and this is NOT a crtitism ), that BA do encourage a great deal of corpoate loyalty. This loyality seems to have coloured a few views. Atitudes like this were very similar in bmi for a while. M Bishop had a very loyal following which was subsequently rudely dispelled for many.
