Like Sun Tzu once said, know your enemy. And what better way for a human rights charity that called itself "Fight Against Slavery" to do its job than to, ahem, obtain first hand experience in handling slaves unpaid personal assistant.
In this ironic job listing from 2017 (which is most likely apocryphal), a newly minted charity purportedly tried to find a personal assistant with an unpaid internship position.
This reminds me of that joke: crimefighters fight crime, firefighters fight fire, what do freedom fighters fight?
