Indeed
She is fretting as it has manager in the title.
I have told her that means absolutely nothing 
Well in general it means
- you're the one that gets the blame
- you're the one that's supposed to be first to buy any round in the pub
- and be the first to leave so few have to buy you one
- and then they can stab you in the back
- when they say 'oh good it's Christmas' you're the one that thinks 'oh shit it's year end'
- etc
