OK yes, pilots are waay overworked because of the limited number of them. That has nothing to do with actual flying

Edit: From your article - “Concern over pilot fatigue was one of the primary reasons that ALPA was created back in 1931, when operators regularly engaged in ‘pilot pushing,’ forcing pilots to fly long hours to maintain demanding schedules,” said Capt. Brian Noyes (United), chair of ALPA’s Flight Time/Duty Time Committee, which is responsible for educating ALPA pilots about the risks associated with fatigue and the regulations and safety programs currently in place to help mitigate those risks.
