If i remember correctly there's a way to let FB know to never let her send a request again. I think you have to go to the main friends page where you decline, and it'll have some sort of, "do you know this person IRL?" And if you press no she won't be able to fr you again.

Doesn't she realize that if you friend her, you can't post passive aggressive online rages about her behind her back? Where's the fun in that?

You can use settings to make yourself invisible. Just block her profile and make it private.

I should make another acc and friend your boss but never use tht acc

Click the "I don't know this person" button when you reject her request and she'll never be able to send yo a request againt.

Seems like a HR (Human Resources) problem

Of she's bothering you that much, quit, unless your looking for a new at the moment, and can't quot til you get a new one.

Block her...if she looks for you you will not be found

I would just block her. If she asks, say you no longer use facebook :)

Reject the request and then block her so she can't even find you to send you another.
