Petered (what happens after the Peter Principle)

When people reach their level of incompetence through promotion, they don't simply stagnate as the Peter Principle suggests—instead, facing career pressure, they may take risky or unethical actions to prove their value, such as performing morally questionable tasks or sabotaging superiors to create advancement opportunities. These "petered" leaders become real imposters who must maintain an appearance of competence while actually performing unrelated, often illegal or unethical work, using obscurity and busyness to hide what they're actually doing. The result is that incompetent leaders become threats not just to themselves but to everyone around them.
