Sure, but so does the word "unbearable." If your workplace is unbearable, you will probably need to leave sooner or later - either because you found a way out or because you burned out. Whatever GGP did might've saved their hide, but it probably didn't result in a "bearable" level of stress (indeed, they said it was "wrong", so it probably gnawed at them). Stress has a way of diminishing your capacity when you need it most. Better to act sooner than later.
