I have a friend who teaches at my child's school who is also on my friends list on facebook.
Recently I have noticed several status updates from her which have clearly been made during the school day, while she should be teaching children. And they're not positive updates, things like "just so fed up, wish it was the end of the day already," and "have had enough now, roll on the weekend, can't wait to get home."
While I'm fully aware that this woman has the right to update her facebook if she's having a bad day at work, she has several parents on her friend list, and I don't think it's appropriate that she is essentially slagging off her job in front of the parents of the children she is teaching.
I have casually said to her that maybe she should be careful what she writes and when, (these posts aren't made during break or lunch times judging by the times of some of them,) and she has just laughed it off.
But I am A not happy that a teacher is spending their time on facebook when they should be teaching my child, or facebooking about how much they dislike their job, which is teaching my child.
