Pros
The benefits are nice, including the 403b.
Cons
There is defiantly a social class hierarchy here at Fermilab where the PHD Physicists are gods and everyone else is a lower form of life, the culture is rife with unchecked egos and often times toxic with . There appears to be no accountability at any level within this organization; under performance and incomitance are allowed to fester almost in perpetuity. If you have any ambition, drive, or lofty career goals then Fermilab is really not the place for you. On the outside one would think or even would assume that Fermilab would be a well managed, technically advanced, highly organized, and efficient organization; but that assumption would be false. Outside of the science being performed at Fermilab the operations side of the organization currently lags that of general industry by almost a decade or more at all levels. This is the organization where careers come to die.
