A Marine staff sergeant inquires: What's it like out there in the civilian workplace?

Here's a question from a Best Defender that I answered, but
am passing along (with the permission of the sender).

I am a Staff Sergeant with 12 years in the Marine Corps
whose "fun meter" has bottomed out. I have received a B.S. in Finance
and am working on a HR certification. I read your post from November 2nd about
a former Captain having difficulty with veteran hires and it concerned me.
I have spent the last few years preparing myself to separate from active
service and am excited about a future working for a company where I can truly
feel like my efforts are helping the company succeed. Is the idea that I can
leave the military and become an all-star for a company a fantasy in today's
business climate?

My response was that it's tough out there, but that he might
have luck with a company with a reputation for hiring Marines. Suggestions?
