Management doesn't trust the employees and generally thinks all employees are stealing secrets and sharing them with the competition. Why would they think that? Because that's how this company got started! If you want to work where you aren't trusted, where all your emails are read and where you are not valued, this is the place for you!
The co-workers are great although everyone walks around in fear of being caught saying "hi" in the hallways. Yes, you can't even say "hi" without being told to get back to work.
