If you're reading this blog post, I'll bet that you're at work, on company time. Should you feel bad about that? I'd like to believe that what you're reading has value, and will add to your understanding of today's workplace and HR practices, and maybe that's justification enough. But I wouldn't be surprised if, besides reading blogs, you also looked at your Facebook account and maybe even sent a few tweets while at work. What's your justification for that?
