One rule I would fully trust AI to make a call on is managing and monitoring employee attendance and time tracking. This is because AI can effectively log working hours and detect absences. If escalations are noticed, it can send automated reminders to employees. In addition, since AI is unbiased, it can enforce the standards and rules for everybody without favoritism or neglect.
One rule I would never trust AI with would be taking care of workplace conflict resolution. More often than not, disputes between employees require emotions, personal experience, and observations which are beyond comprehension for AI. A human mediator is essential to listen, analyze, empathize, and make context-based decisions that ensure all angles are fairly considered. AI may misread sarcasm, tone, or intention, and cause an unfair or unfriendly outcome.
