If we are examining ridiculous arguments start with the expressed sanctity of family time on holidays that some how is then quantified in dollars and cents.
If you dont want to work holidays and weekends....get a plan to bid to a base and category wher you can most quickly make that happen.
If your view is working holidays is a qol hit....because of the invaluable lost family time...how does getting paid more fix that? You are still away from family.
So to 'fix' your qol problem.. we either force delta to not operate on holidays....not likely.
Or you adjust your personal situation to minimize your exposure to holiday work.
Oh...and fyi... fdx doesnt have a 60% fae pension.
