Pros
Currently am contracted through intercon to a philanthropic organization. This contract has fairly competitive pay, twice annual bonuses, and a relaxed work environment. You can easily rack up a lot of experience in various areas of security contracted to reputable organizations that will help open up your career options.
Cons
However, my manager doesn't manage me at all, nor does he protect me from the client. This has been an issue not just my 4.5 years in my current role as security manager, but my whole 9 years with Intercon. Nor does he respond to any of the interpersonal issues that are escalated to him. Why someone who isn't a people person at all is a manager is beyond me. There's no concern or seeming interest in the actual wellbeing of the employees. So big issues fester, and morale is perpetually low.
