lol @ update 6, never underestimate ego and fucking incompetence in the corporate environment.
4 months ago I left a position for similar reasons. They decided to re-org a perfectly working and fluid department (this happens way too fucking often, I'm sure you guys can relate) and split it into these two stupid teams that made no sense and basically cut my ability to do my job in half. Two of the other engineers left because of it leaving just me to handle all the responsibilities of the new team. Hilariously though, they expected me to continue to do work on both teams because they desperately needed me and my help but they just didn't want to have to pay me for it. I decided to give them a firm response.. either promote me and pay me more (I only asked for 4 or 5k more a year) for doing the job of two people, let me switch to the other team since majority of my work and interest lied there anyway, or I'll find another gig.
Long story short, they called my bluff and said go for it.. I had another job lined up and I put in my two weeks. They went to 0 engineers who knew how to do my job and had no one to replace me. Last I heard they were paying thousands of dollars to consultants who still don't understand the system. My old boss emails me from time to time asking me for advice or help on the environment... never underestimate how fucking stupid non-technical management is. Instead of spending 4-5k or letting me switch to the other team for FREE, they've blown 10x that amount. Golf clap.
