Low level employees get very little responsibility and must work hard to earn the trust of their management. I really felt as though I was a cog in a vast machine with no hope of rising quickly through the organization, and this was within Raytheon's Leadership Development Program. I was not even close to developed as a leader there.
The superstar culture coupled with the vast manufacturing required to implement the technologies developed there, unfortunately requires a vast infrastructure in which many many employees contribute only indirectly to the advancement of any technologies. As a result, systems become entrenched, employees are not empowered and a huge number of people work in "support roles".
