Is my soldier wrong? "per regulation he must inform the chain of command if he is put on quarters."

I'd would take it as a teaching point to the soldier on communication. He trusted the words of an Officer. He should be taught that that is all good....but.....he should also make sure that information flows through the enilsted channels also. It is an easy mistake for a new soldier to make...just lead and guide him as you are already doing. let him know that information flows up hill...not down in the military.

Yes he is required to report to the CoC regarding quarters. Being that the PA in your clinic did inform the PSG that meets the spirit of the regulation. If the PA told the soldier he would let the PSG know then the soldier did what he was told by an officer in his clinical chain. He should have let you know as a courtesy, but if the PSG is informed that should suffice and the PSG should let you know. I agree with SMSgt Eric Johnson Jr. His advice is spot spot on IMHO.

SGT. Talavera, as a DoT employee who works in a hospital taking care of soldiers and an Army veteran, the PA took full responsibility in contacting the PSG and sent the soldier home. From that point forward, it was the PSG's responsibility to contact you and your first line to inform you of the soldiers status. You have to remember that the PA out ranks the soldier and I'm sure your soldier assumed that they were good-to-go because of the orders given to them by the PA. My suggestion to you would be to sit the soldier down and have a talk with them. Inform them of what you want regardless of what the PA says. Also on the other hand, let them know that you understand that they were following orders as they are suppose too. I would just explain the whole "accountability" issue to them and I'm sure they will understand.

If I am not mistaking, there is a portion for the commander to sign. It's more for accountability than anything else. But, if I were the Soldier, I would have let my first line know. The last time I got quarters, I simply took a picture of the slip, and texted the picture to my OPS. She emailed me back saying she got. ACCOUNTED FOR!!!
In this Soldier's case, I would not get all worked up. He didn't intentionally do the wrong thing. A verbal counseling should suffice. No need for paperwork.

Is there any reason why your PSG did not inform you of the soldier being gone. Communication is a 2 way street. As a PSG, I would have informed the soldier's first line leader, if I found out he was sent home sick. The problem you have may be coming from the other direction.

There's too many people to respond to, but I want to thank each and everyone of you for your input. It's been a big help.

Yes you must infirm the chain of command

He should have notified his chain of command as common courtesy let alone mission requirements (ie- who is doing his job when he is absent).

Seems like an honest mistake, nothing to fry the SM for, unless there is a history of this kinda thing. The PA should have done more than an email and the SM should have told the NCO above him. NCOs are in charge of the manning and day to day activities, not an Officer.

In the Navy and Marine Corps, where I am, E-5s are always the first to know. In fact, they are typically the only ones who know unless it's brought up but someone higher up. If you can't let an E-5 know, let the nearest and highest ranking E-4 or below know so they can notify the E-5. If you are dismissed or sent home by an E-6 or above, you are still supposed to let your E-5 know, since they are typically your direct supervisor. So, based on my short experience, I would absolutely say you should've known much sooner. The Soldier should've let you know on their way out.

I would say your Soldier is both correct and incorrect at the same time. But, there were a few balls dropped here, per say. Yes, your Soldier should have informed you he was leaving (as professional courtesy and accountability at a minimum), but then he was following the orders of the PA (who is an officer). On another side, if you/your Soldier/PA all work in the same area, then the PA could have easily informed you of him releasing your Soldier. And another hand was (granted your PLT SGT has a lot on his plate) the time frame in which your PSG should have informed your first line sooner.

With all that being said, accountability was still being maintained since the PA informed your PSG. I would not be too hard on your Soldier about this. When you next get a moment simply pull him to the side and ask him to inform you of his departure if something like this were to happen again. Simply stress that accountability is key when it comes to all aspects.

This is it. No mention of who must talk to who...
