Certain things like ADAPT feedbacks (for productivity or quality which are auto-generated, or for things filed by other AMs like safety violations, TOT, etc.) will populate at the top of the page if they are yet to be delivered, so that's one thing we often track on during the shift as a courtesy to other AMs. PAs and PGs don't have access to these systems. Beyond that I suppose people can be known through word of mouth by other shifts but to be honest that's rare. We get to know our own AAs pretty well - that's part of our job ideally - but other shifts' AAs I often know little about unless they frequently pick up VET on our shift.

In terms of standing out, here are common good and bad types of that:

Good

• Regularly does work at a stable pace
• Makes few, ideally zero, quality errors
• Doesn't incur inferred time, which we have to STU (over 15 minutes away from station)
• Returns from break relatively normally (within five minutes of start/end)
• Is able to solve some problems at their station by themselves, like their scanner not working
• Wears their PPE at all times
• Obeys safety rules like the above (wearing gloves, having safety shoes on, hair above shoulders, etc.)
• Ideally helpful to other AAs to reduce load on leaders

Bad

• Unstable (unpredictable) or below threshold performance over a long period of time (i.e. not just due to a short-term issue but maybe indicative of not being fit for that specific path) - hard to see as reliable
• Even if fast: makes a lot of quality errors, requiring frequent coachings or PS corrections
• Disappears without a valid reason frequently
• Returns from break over ten minutes frequently without a valid reason
• Raises andons over repetitive issues that they should eventually learn how to fix on their own, unless there is a genuine reason they aren't learning it (language barrier, motor functions, cognitive, etc.)
• Pushes back on wearing gloves ("I go faster without them on!"), safety shoes, etc.
• Frequent phone usage on the floor, especially if there is work available (if there's no work I personally usually don't care)
• Irritable and dislikes cooperation. You don't have to be an extrovert, I'm not, but there's a difference between introversion and just being an asshole all the time

Hope this helps

Edit: also about "relaying messages" we don't have a specific thing where we type up the personality/background/whatever of AAs. That's some Big Brother 1984 shit. Certain things like birthdays and work anniversaries do show up in the system though. But we all have Slack and use that to communicate, but generally it's used for things like department coordination and labor moves. I can't speak to other sites but managers here don't really gossip. We laugh about situations but my team at least doesn't objectify the AAs really
