How can I help someone when their performance has changed a lot?

People come here to understand why something in everyday life feels harder, different or more costly than it should — and what might make it work better.

Short answer

A change in performance can be a change in conditions, not a lost ability.

What this can look like

They may still be skilled, yet produce less when the work has more noise, change, unclear priorities or too little recovery.

Why it can happen

Compare the work, environment, interruptions, recovery and health context around harder days. That produces a more useful conversation than “what is wrong with you?”

What might help

Compare better and harder days together. Change one condition—timing, interruptions, scope or written clarity—before judging ability.

What the research helps explain

WHO describes burn-out as an occupational phenomenon linked to chronic workplace stress that has not been successfully managed. Australian guidance recognises that workload, control, support and work design affect wellbeing and performance; they are not simply personal resilience issues.

What can vary

Fatigue, cognitive changes and reduced capacity can have many causes, including health, sleep, medication, stress and caring load. A public page cannot diagnose burnout, depression or illness; new, severe or concerning changes deserve appropriate advice.

For this situation

For you, describe the specific job that changed and ask what would make it workable again.
