I suppose the reason this piece strikes this community as so silly is that the general philosophy of the startup is that a group of 5 or 10 people can best multi-million dollar corporations because corporations are so inefficient. To turn to such a company's firing decisions as the source of truth of worker quality feels profoundly backward.
If they are going to do a study on the impact of toxic workers on the workplace, surely they should do one on managers.
* Grandiose sense of self-worth
* Pathological lying
* Cunning/manipulative
* Callous/lack of empathy
