I had this as my facebook profile for a while after kicking my ex out, apparently it pissed her mother off because she showed up at my work and bitched at my boss about it.
That's a real good was to get arrested for trespassing and get out on a local municipal law enforcement watch list.
From the sounds of things though, I'd say that family already was.
Unless it's a retail job where people can go to that place. Also, you can be fired for social media stuff, because even off work, you still represent the company. Have fun with this little shitstorm. :P
It was a retail job and I had already warned him about that bunch plus had a valid restraining order against them so they actually were not allowed there (they are all a little unstable) As far as posting stuff like that as long as I didn't post anything confidential to the company my boss didn't give a shit.
