Devils advocate :
How does moving drivers from the braz to the dirty Fokker benefit the company? Let's say a captain moves from the Braz.
He/she will need to be trained on the jet = time and money.
His/her replacement would likely be an existing FO upgrading = time and money.
The replacement would also need to be replaced, a new Braz FO = time and money.
Or
Employ a direct entry onto the jet, much easier and cost effective.
Sure some may leave but the company would likely prefer the risk over the above scenario. Morale is damaged but can anyone truthfully say they have worked where morale was important to the company? These things cannot be put into a spreadsheet.
That is the reality folks, it sucks for us but generally the goals of business do not align with those of the employees.
