Not if they had the wrong frequency tuned in, and they were both busy arguing about union stuff.   Seems a "we fell asleep because our schedules were gruesome and we were fatigues" would have been the easy/best answer.   INstead, they insisted they weren't asleep, and were on the wrong frequency while "reviewing" their flight schedule bidding process.   And, ironically, the CVR didn't have any history on the loop because the microphone must have "malfunctioned".

This is hardly a case for fatigue, hardly an accident, and hardly Part 135.
