Congrats. Hope the transitions not too rough from being ' one of us ' to ' one of them '! People are so amusingly tribal in nature but we love to forget we are just animals with bigger brains.
Just try to resist the urge to start swinging your authority around the place and changing shit just for the sake of it.
Brilliant news in this awful job climate. Are they replacing you with a new employee at all cos that would be a double whammy then!
