This thread seems to be drifting into a discussion about 'mystery shoppers'. The threat of strike action is still very real in BA so why not start a separate 'mystery shopper' thread?
I believe that there are people in the BA legal team who disagree with emanresuym in the interpretation of the 28 day rule (post #855). If another strike is called I think that you will find that the validity is challenged in the courts. The wording of the act is by no means clear.
