1) Minimal job security. Once they lost one of their two big contracts, stuff hit the fan. I'm still not clear what led to the contract loss - I have an inkling that the client relationship was mismanaged, but it could just be bad luck. Either way, it destabilized the company deeply, and Navanti has yet to recover.
2) A CEO who rewards sycophants. Some of the more obnoxious analysts have now managed to rise to middle management positions, fueling their power trips, solely by sucking up to the CEO.
3) An undercurrent of racist and sexist behavior. Female analysts were almost never given management roles, and may have systematically been paid less. Linguists, even when bright and talented, had no advancement potential.
4) Not enough care taken to manage the risk that local researchers take. To this day, I have no idea what Navanti's policies would be if a local researcher were to run into problems while performing work for Navanti.
