We BA crew 'made our bed so should lie in it' - so why should BA pull the sheets from underneath us? As you say, we signed up for it, so why should it be changed?
BA are very good at pulling sheets, and changing things, make no mistake, ask any of the Old Codgers who have had the sheet of Staff Travel pulled from under them recently - who also signed up to certain terms and conditions, albeit before some of you were born.
Sorry, I sort of promised not to raise the S.T. issue again on this thread - I couldn't resist that tho' !!
I accept that S.T. is very small beer in the present situation, my interjection is to assure you from personal experience that BA CANNOT be trusted to keep their word.
Best of Luck.
