The trick of corporate survival, as observed in those who can actually hack it, is extreme compartmentalization. They become two people: one who watches the abuse from a distance as if it were happening to someone else, and then a normal self that is functional enough to do the grocery shopping without bursting into tears. The problem is that very few people can sustain this compartmentalization (also known as: dissociation) for more than a few years. It tends to play out badly (memory issues, alexithymia, autoimmunity) in the long term.
