Should I pay for short-term disability through my employer?

What things should I consider when choosing to pay for short-term disability through my employer? It costs $17 a month, kicks in after 14 days of being out, and then starts paying 60% of my salary. I work in IT, so it's not like a physical injury is going to keep me from working like it would if I were in a blue-collar job. Should I just pocket the $17 and hope for the best, or should I seriously reconsider paying for it since I can afford it?
