> Example: the director/founder of one NP I know of that had a mission of helping pregnant women in crisis forced her 8 months pregnant employee to walk for miles through DC and do manual labor for her. She chewed her out in front of the whole team for saying she wasn't physically capable and made her cry, demanding that she do something that was technically her (the director's) responsibility.

That sounds Dickensian to the point of parody. I would do whatever I could to raise awareness of that insanity to the board of any non-profit, were I to witness something like that.
