I have to disagree with some portions of this article. Working as a musician is waaay different from working at a corporate sweat shop. This whole "work ethic" rant is a little misleading, especially pertaining to music.
Summary: Complaining achieves nothing. Figure it out.
When someone throws around the phrase "work ethic" too much, I tend to start looking for the other hand with the knife in it as they're usually looking for their pound of flesh, and it's usually from the person whose work ethic they are questioning.
