Why can't they see that the workforce is shattered by low morale?
Why would they care:
Look at it from the Shareholders / Management position. The flights are still departing on time with bums on the seats and they are paying their workforce a below average wage. As a result they make a larger profit for themselves and the company looks more attractive to future investors.
With new entrants paying towards their type rating and being paid a Dash salary while flying a 146, plus the savings from new f/o's i.e no increments to pay the company are saving a fortune. It is also a fact that new guys will be far more willing to help out by putting up with more roster disturbance and working days off than the more senior guys they replace and therefore can be utilised far more.
They are the clever ones no wonder they couldn't care about morale.
