It's not really an informative example. You're not losing your job in this case for emotional harm. It's because you insulted your boss. You could lose your job even if he didn't care.

If you had to let an employee go and caused even more emotional harm (brought on by their no longer being employed), you wouldn't receive a reprisal.

Why are you pointing out that speech sometimes is reasonable to punish? How does this clarify the question of whether we have become too punitive regarding political and controversial social speech.
