Thank you, guys.
I agree, for what it's worth. But seeing as I'm the lowest man on the totem pole, I can't very well go telling people this, at least not if I want to keep a job. I am thinking it very loudly and petulantly, though. <_< There is a distinct lack of "manager" in my title. In fact, there's a very prominent "Assistant." As in, assisting.
I will admit that I could have confirmed before I threw things out. I will also point out that my boss is extremely busy and always very flustered and frequently can't or won't answer my questions when I ask them
anyway, and my boss's boss (the one who is most upset about this and the one to whom my boss would then direct my question or me) is gone every Thursday and Friday and in meetings or at appointments 75% of the rest of the week.
Anyway. This is How Things Are(TM) and I need to deal. So says my boss. So says my sense of self-preservation. Whether this was my fault/responsibility or not, it's what I have to deal with.
Believe me, though, I am actively working on setting up a situation that better appeals to me, i.e., finding a new source of income.
