My job is fairly unique as it involves waiting for various situations to occur. If they don't I pass my time playing on here. That isn't sad, it gives me something to do in between jobs . I can be away for minutes, days or not at all, depending on circumstances. I always am near a PC unless the situation requires me to act suddenly.
I am employed but manage myself and work in a small team of 8, and am judged not on results, but have to be effective as more of a deterant than anything else.
Sometimes I dress similar to others. Sometimes casual.
