The issue of confidentiality already being breached on so many levels, though, DOES give me pause .. If this were my man's situation, I'd counsel him to wait till the dust settled and he was able to think more clearly and FEEL more CALM about his next steps. It sounds like you've already reached SOME resolution at this point, and explaining further might just muddy the waters. People who DON'T understand PTSD (in ANY of its complicated forms) might jump to other conclusions about how they read you, and thus read INTO this or that reaction you offer something that might not even be there. (You might "feel" less in control than you actually are - it's ok to not show all your cards, in this kind of situation.)
It sounds, at this point, like this needs to be treated as a communication issue, and your team members need to come directly (!) to you with any concerns, first. You know it's going to be WAY better for you to react if they bring a genuine concern for you, than if you get broadsided by upper management or HR with something that sounds much worse than it really is .. So what could you do to cultivate that sense of "trust" with your team members so they feel more open? .. Sometimes just occasionally [privately, if possible] ASKING them for their feedback - checking in once in a while .. "How am I doing as your manager/supervisor? Do you have any suggestions for ways I could improve? Do you wish I were doing anything differently in terms of how I'm communicating with you?" etc.
That by itself might be all they need to hear to feel "trusting" or more open with you, and then you could deal with any snags along the way on a case by case basis. It might also be helpful to document any conversations in a planner or notebook (or online schedule).
Example: I had a conversation with so and so on this date; I asked this (a), he/she responded (b), we agreed that going forward I would (c) and/or he/she would (d) ... and then be sure to follow that plan.
Document as consistently as possible. Even if their response is "No, you're doing great!" Cuz then if HR comes back, you've got a trail that proves you couldn't reasonably be expected to know that there were any problems - so and so TOLD you they thought you were doing great. (see?) It doesn't need to be complicated, just consistent. You could set a personal goal of having a conversation like this on a quarterly basis, or every month, or whatever REASONABLE timeline works for you. :)
Speaking AS a manager and supervisor with teams of people under me in the past, your situation would have been a trigger for ANYONE - PTSD or no! - and the stress attached can be AWFUL. Just awful. :hug: But it doesn't sound to me like you "owe" any further explanation - and the only reason to disclose more about your own trigger points should be only if you feel COMFORTABLE that their knowing won't come back at you as a threat in other circumstances. Based on how the complaint was both made by the people involved AND by how it was handled by the powers that be? I would not feel comfortable disclosing too much personal info .. It might only create further (unwarranted!) prejudice. You're obviously doing great on the job to be IN the position you're in. So KEEP UP THE GOOD WORK!! ... :)
Not sure if any of that helps?
