The SRG has just modified CAP371 to stop rostering monkeys driving a coach and horses through the SPIRIT of a document that is there to minimise fatigue. If the revised programme cannot be carried out within the requirements of CAP371 from the beginning of the standby period it must surely be considered FATIGING. Your actions would be looked at very carefully after an incident (and there have been a few recently where fatigue has been a factor)
Can I remind you that a man is spending 6 years(actually 3) in prison for falling asleep while driving a car. Remember that the person whose roster you are changing is going to be "driving" with anything up to 350 passengers behind him. Start taking the job of rostering seriously: Safety is always supposed to be a the first priority - put it were it belongs.
