So don't you do it either.

At last night's Nerd Nite London, which was the TMP Women's Network field trip this month, we heard a talk on the similarities between apes and humans. I was reminded of a 2013 TED Talk that showed capuchins have cracked something we humans haven't: they refuse to work for unequal pay.

They really refuse. Like, I throw your unequal pay back in your face refuse. 

It's a really funny video. And a satisfyingly clear experiment to observe. And a pretty straightforward lesson for us homo sapiens: Don't let them get away with it. Demand what you're worth.
