It's highly interesting but my one job keeps me more than busy enough, thankyouverymuch.
Edit: A few other thoughts I had since hitting submit:
1. It feels to me like the most challenging part of living a double working life is making sure your mandatory meetings at each job don't conflict. I wonder how people get around that?
2. Many (most?) employers already have a "no moonlighting" clause, I wonder how long before there will there be explicit legal language stating you cannot have this full time job plus another full time job?
3. I believe there are a few places in the tax code where there is a difference between having a full-time job and a part-time job, are there any areas where you would have to lie to the govt when you have multiple full-time jobs?
