Everything else. As a DoD contractor, I worked on a Naval Base. Our office was inside an old storage room and vault. The main problem was our management was in San Diego, California and our job site was in Hawaii. There was next to no oversight. The immediate management not only condoned, but participated in unethical behavior. The most common was time card fraud - reporting time worked when they were not there. Especially taking excessive breaks, leaving early, etc.
The building was classified Secret, and our workspace was Top Secret. This requires a ban on any communication or recording devices. Boss & colleagues routinely brought in and used mobile phones, and even USB drives.
The resources (phone, computers) were often used for personal tasks, to the point of creating a loss of productivity.
We had quarterly corporate ethics training (web-based), and afterwards the (local) managers would tell us to essentially disregard the policies.
I was threatened with physical violence after I reported a colleague for ongoing unethical behavior. When I tried to escalate the situation through upper management, I was told *I* should consider finding a different job. Because I was "the only one with a problem with not following procedure."
I was intending to give my notice when the Dept of the Navy declined to renew our contract, especially in light of recent SAIC employee practices.
I can't speak to SAIC as an entire company, but any time there is not clear management you invite problems. I would be extremely hesitant to work for them again. The people I worked with were truly the least ethical & professional colleagues I ever had.
