I'm the proud recipient of getting that 2X raise, but not until I gave two weeks notice. (Former attempts to get a raise resulted in regular 0% increases.)

I agreed to stay for four months more. I knew a 2X raise couldn't win against my psyche forever. But it was nice to finally get that formal sign of acknowledgment.

(Former signs of acknowledgment - aka monetary bonuses - sat in my direct manager's desk. He never felt the need to pass it on until it became apparent to myself and the person who directed it that I had not yet received it.)

I don't know about the skeeziness of the writer's boss, but my mine sure was!
