slave-driver manager; heartless section chief
Colloquial, often half-joking term for a strict, demanding, or unsympathetic boss. The 鬼 (oni) prefix intensifies the harshness.
Our slave-driver manager gets angry the moment you refuse overtime.
All the new employees are scared of that heartless section chief.
