Ventajas
Reasonable stability. Lockheed Martin has had this current contract for over 13 years. There is some flexibility in the work hours. As long as you hit your 40 hours per week you're ok. There are a lot of pretty smart people working here, so the ability to pick up additional knowledge is available.
Desventajas
Very political. Poor communication. The thought that because they have a "plan" for communication, they're actually communicating. Too many obstacles to getting the job done. The idea that the employees are simply plug-and-play commodities. There is no thought to growing their employees. They simply hire someone to fulfull a need, rather than provide training and opportunity to their existing employees. Tuition reimbursement is a joke.
