That isn't "hacking" as defined by the CFAA (according to this ruling). It's certainly not following your employer's policies, but your employer policies should not rise to the level of potential federal criminal prosecution. Now, if your employer put software on your machine or on their network that prevents you from viewing Facebook, and you work around that restriction, it could be argued that you have now "hacked" their network and gained access you were not authorized to have. The distinction is pretty clear in the ruling - if you have access, you can do X without it being considered a violation of the CFAA (doesn't mean you can't be fired, or prosecuted for other crimes leading from the actions, or other repercussions). If you don't have access, and you figure out a way to gain access, it is now a violation of the CFAA.
