              "content": "Two months of changed behavior — especially in someone who was presumably performing well before — usually signals something is going on *with* the person, not just their work. Here's how I'd approach it:\n\n## Before you meet\n\n- **Gather specifics.** Missed deadlines, quiet meetings — note 2–3 concrete examples with dates, not vague impressions. Vague feedback is hard to act on.\n- **Check your own assumptions.** Has anything changed on your team: new projects, a reorg, a colleague conflict, unclear expectations? Sometimes the manager *is* the cause and doesn't realize it.\n- **Talk to peers carefully.** A quick read from collaborators is fine; don't build a case file.\n\n## The conversation\n\n**Do it privately and early.** Don't wait for a formal review. Something like:\n\n> \"You've historically delivered on time and been active in discussions. Over the past couple of months I've noticed missed deadlines and less engagement. That's not like you — what's going on? How can I help?\"\n\nKey points:\n- **Lead with concern, not accusation.** \"Is everything okay?\" opens more doors than \"Why are you missing deadlines?\"\n- **Listen more than you talk.** The most common causes at 26 with a sudden dip: burnout, personal issues (health, family, relationships, mental health), feeling stuck or under-challenged, or confusion about expectations they're afraid to voice.\n- **Don't diagnose.** You can ask \"Is there anything affecting work I should know about?\" but don't probe personal details or speculate about mental health.\n- **Share the impact, not just the observation.** \"When the API slipped, the QA team was blocked\" is factual, not punitive.\n\n## Afterward\n\n- **Agree on concrete next steps** with a check-in date 1–2 weeks out. Change rarely happens from one conversation.\n- **Adjust workload if needed** temporarily — it's cheaper than losing someone.\n- **Document lightly.** If it continues and becomes a performance issue, you'll want a record of early, supportive intervention.\n\n## What to avoid\n\n- Publicly calling out the quietness in meetings\n- Assuming laziness or bad attitude\n- Waiting for the pattern to fix itself\n- HR-formal performance management as a first move (save that for later if support doesn't work)\n\nMost of these situations, caught early and handled with genuine concern, resolve within a month or two. Would you like help scripting the actual conversation, or thinking through what to do if they deflect?",
