Yes, but even there the consultant made a point about making the transition as smooth for the fired person as possible. The whole point was not to stir up negative emotions, which by their very nature are unpredictable.
Sure, but the client still pays the consultant for economic reasons: soften the emotional blow to the employee being let go in order to soften the reputation blow to the company. If the employer does not care for reputation (or, what seems more likely in this case, key persons might actually like that particular type of reputation), why would they pay?
