Pros
Not much, I will say I had great direct management. It is unfair to say that has anything to do with ASM though. The management was already in place before ASM took over.
Cons
Honestly I don't even know where to start. As an overall perspective they really make you feel like you're 100% replaceable at any time. There is no room for advancement what so ever. Nobody at ASM cares about your carrier development. I worked at the NSD for the VA. As soon as ASM took over the contract our call volume jumped up dramatically. They let go of a bunch of high quality techs because they made too much and hired a bunch of people with no experience in the IT field. It's not fair to both the VA and the new employees. The VA and our veterans deserve better than that and the new employees were never given all of the details about the job. They set all of these new employees for failure. Because of all of this it's our veterans that will suffer.
