Passive aggressive sexism

I’m kind of obsessed with the site Passive Aggressive Notes; I think it’s hilarious. This one I found particularly irritating/interesting:

Apparently this woman’s supervisor sent this charming note because someone had been complaining (!) about her showing a bit of cleavage. According to the sender, “as I’m currently 7 months pregnant, i could be wearing a turtleneck and still be showing ‘too much’ cleavage.”
Ugh.
