Not sure where the (as I interpret it) aggressive attitude comes from, but I think you'll find that those whose ARE working / volunteering will be motivated, professional, respectful and overjoyed to be keeping BA afloat and working as a team; irrespective of their background.
You'll also find, whether you like it or not, that the Captain WILL be your boss on the aircraft. Legally! However, they are always professional and treat their crew with the utmost respect if you do the same to them. Treat people as you'd like to be treated yourself is my belief.
