Don't do what teenage Kimberly Swann (pictured) did, in which she posted comments over a week complaining of the task she was recieving to which she was called into her Employers officed and fired on the spot with a written explanation of the reason for her termination from employment. The letter read:
'Following your comments made on Facebook about your job and the company we feel it is better that, as you are not happy and do not enjoy your work, we end your employment with Ivell Marketing & Logistics with immediate effect.'
There are simple ways that events such as the one that befell Kimberly Swann can be avoided, keep Facebook personal! Don't accept that friend invite from your Boss or colleagues you're unfamiliar with and even then if a friend is also friends with the Boss and they comment on an update in which you've complained about your job your boss will still see it, so always consider what you're going to type before hitting return. Next is put your profile on limited view by simply adjusting your privacy settings to friends only. I guarantee this will save a lot of grief down the line, whilst you're closing yourself of the the odd chance of networking with new people you'll have complete control over you sees your profile. Do you really need 400+ friends on Facebook or just a good 50+ mix of close to moderate acquaintances?
