Hell, we just had a manager who was under a lot of pressure last summer for a huge release. He had a complete breakdown and after four months off, he came back, took a demotion, but he's not the same guy anymore. He used to have a really outgoing personality and loved to talk about his band and music. Now he just nods when you say "hi" to him and keeps to himself.
While I applaud management for working with him and being patient during his recovery, I'm still wondering why other managers didn't raise flags before he went off the cliff.
For me, the larger problem is how do we stop this from happening? How can we stop these situations before people get to a dead end? For some of these people, it's really serious and something you don't ever come back from, which is really, really scary to me.
