Part of the reason we declined to continue the extension to trying VBs was the company was handling SILs in a manner that benefited few at the expense of many more. Trying to find the bottom of how low pilots would go on compensation (40 hours? 25 hours?) to take the month off. They said they were doing this in categories that were overmanned....AFTER declining RCC requests in the same category. Those RCC requests conveyed the wishes of pilots looking to improve their QOL but the company wouldn't hear it. The union also asked that overmanned categories yield more vacation weeks in those overmanned months (another seniority-honoring QOL enhancer)... to no avail. Since the company sought to solve manning imbalance only by lowest-bidder SIL seekers while telling DALPA to pound sand regarding solutions pilots actually wanted, I fully supported their halt on VBs. Good learning on both sides.
