exactly. “fully staffed” has a different meaning to everyone, and definitely to the company.

if we are one reserve into blue territory all month at 0659 on the 20th, are we “fully staffed?”

at 0715 on the 20th when people have dropped trips and put us all black again, are we “understaffed?”

is “fully staffed” determined by the ability of anyone and everyone to drop any trip they see fit?

arbitrary indeed, which is why i asked what it means to the person who said it first
