I always hear from time to time that people delete their Facebook accounts because of many reasons, and I can understand that. Certainly, Facebook isn't for everybody, even though it works for about 1 Billion people...
However, I've been hearing a lot of people tell me that they've deleted their Facebook accounts primarily because they don't want their employers to have cause to fire them, or get any information on them.
The day that I stop expressing myself of who I am as a human being for 24 hours a day vs. the 8 hours a day that my employers sees me, is the day that I toss in the towel as a citizen. Clearly, if my way of being shows up and doesn't sit well with my employer, than they can kiss my ass when they boot me to the door.
I will certainly not suppress who I am as a person and express it as the law of the land allows, and not because I enable the corporate world to use it as a threat to my livelihood. Express yourself as you want to, and not as you "should" when worrying how others see you.
And here's a tip... If you are working for an organization that you empower, I would ask you to see if they really empower you, or simply just Employ you. If you chose the latter, maybe it's time for you to find some company that wants to include you, rather than you being included by their conditions.
