Pros

Quiet, empty office spaces. The jobs are pretty easy and the demands are low. Most of the "leadership" have been there forever and some are coasting, so that makes things simple. They have pizza sometimes or leftovers from the board meetings available. I do think they mean well, for what it's worth.

Cons

Directors and Junior Execs have been there a really long time and like the way they do things -- don't expect your great ideas to be met with enthusiasm. It's down to a couple of old-timers involved in everything who will tell you how things are going to go. Ongoing layoffs and declining stock price and sales.
