He's not even owning up to his own failure. He's trying to blame this problem on the town manager, and not himself:

'...and hope that the Town of Leland will hire a dedicated human

So, he's trying to say that the town should have provided an HR person to tell him that he can't harass his subordinates.

It's time. As a taxpaying citizen, I demand his termination.
