I was able to talk with him, he's on an SNRI but same thing, it's not a narcotic.
As far as being treated for depression and not having a job, most people at some point in their life will need treatment for depression and I don't think the nuclear industry is exempt from this. He's only been on it for a few months and the doctor is going to start tapering him off it soon. He's always been a normal guy, very happy. Just work stress got to him and he just felt the world caving in on him. He didn't get all crazy and suicidal, still went to work and all that, just was really down a lot.
The job he's in is a huge part of why he got depressed in the first place so I feel for the guy.
Anyway, I was able to find some stuff for him about it in CFR 10. Looks like he can get evaluated by a psychiatrist and be allowed to work anyway. Still don't have a warm fuzzy that I can tell him to go ahead and disclose it.
