High turnover rates are not his fault.

[housepital]

House has gone through eight assistants since he began at Arkham. For various reasons; The first two were idiots, the second one was lazy, the third and fourth and fifth were idiots, the sixth was stealing prescription drugs, the seventh was an idiot and today, the eighth one mailed in his notice without even coming in for his final check. The rumor was that he'd been locked out of House's office and forbidden to return.

Which is why House turned up in the day room not long after mail-call. "Dibrell Membrane, you'd better be in here."
