While working on the company I'm leaving, I was moonlighting in the company I'm going to. Now the tables are turned: I'll be working full time on my moonlight job and then take the old job on a limited contract basis. Basically, I'll still have two jobs as before, but I'm swapping the relationship betwixt the two.

You gotta confuse the PHB's outlook on life every once in a while. Rinse the relationships up and then recycle.
