I have considered it, but no I have not. I was having a few issues when I first started my job, and I was thinking of telling my boss about it. At the time, however, I was only self-diagnosed, so I did not want to tell a bunch of people until I had it made official. When it became official, the issues have subsided, and she seems to understand my "quirkiness". If there is an autism-related issue that arises that I feel cannot be solved, I probably will tell her. Until then (if that ever happens), I don't see a need to do this.
I did have a HUGE issue once a couple years ago, so I did tell a boss then (I was 7000 kilometres away from home, so I felt I had no choice). The boss said, "yeah, I knew there was SOMETHING wrong with you!" in what I perceived to be a very rude tone of voice. I have been known to misinterpret tones, but still, how else can someone interpret the words themselves. That is a very rude thing to say to someone, IMO, even if it is true.... So, ever since then, I have only shared it when I felt the need to.
