Haven't read the INTAM myself so can't speculate.
Currently I'm hoping that it's an error in reading and the purpose of the INTAM isn't actually to blame
every 'engineering' delay on the industrial action. If it's just a matter of fact statement then I've got no problems laying out the facts- I made this comment on another unrelated thread and I'd hope that you guys would see this as us just being honest- but if it's asking me to blame things on industrial action that patently aren't the case or to be disparaging towards our engineers then it'll get treated with the contempt it deserves.
Of course, I'm not out of the sim for another few weeks yet so I won't have to worry about it unless you guys are still going hard in late July! For your sakes (and the sake of the airline) I hope it doesn't come to that!
