A breach of these is a criminal act. So either comply with the bullies and empower them or grow a backbone and inform them of the following
EU. Ops 2.2 'An operator will ensure that for all its flights, flights are planned to be completed within the allowable flight duty period taking into account the time necessary for pre-flight duties, the flight and turn-around times.'
ANO 146 (1) 'A person must not act as a member of the crew of an aircraft to which this article applies if they know or suspect that they are suffering from or having regard to the circumstances of the flight to be undertaken are likely to suffer from such fatigue as may endanger the safety of the aircraft or of its occupants’.
ANO 145 (2) ‘The operator of an aircraft to which this article applies must not cause or permit any person to fly as a member of its crew who the operator knows or has reason to believe is suffering from or, having regard to the circumstances of the flight to be undertaken, is likely to suffer from, such fatigue as may endanger the safety of the aircraft or of its occupants.’
E.U. Ops 3.6. ‘Operators shall ensure flight duty periods are planned to enable crew members to remain sufficiently free from fatigue so they can operate to a satisfactory level of safety under all circumstances. ‘
Therefore, if you are going to bed and waking when you can and you are still fatigued you must therefore be fatigued due the airlines failure to comply with EU Ops 3.6.
