There was an recent interesting MOR listed on the CAA list on a "fatigue" issue, not sure if it's available in the public domain though. It was to do with a schedule that was MOR'd as fatigueing. In response to the MOR a "Senior Management" Pilot undertook the schedule and said it was fine (ok he would do!). Other Pilots were asked for their views and they advised it was "tiring" but not fatigueing. It's worth remembering there is a difference
