Human resources is often described as the custodian of organisational culture. The department expected to protect values, drive engagement, and keep workplaces healthy. But there is a part of the job we talk about in hushed tones, if at all. Managing leaders. Especially toxic ones.
Most toxic workplace cultures are not created by employees. They are created, enabled, or tolerated by leadership. HR often sees these patterns early. The quiet exits of high performers. The whispered warnings from employees who are scared to be named.
