I thought it was a seriously Bad Thing that Bob Mansfield was retiring from Apple, and it looks like his employees did too.  We didn't know how badly until recently.

Bob Mansfield stayed at Apple after CEO Tim Cook offered him 'exorbitant' $2M-per-month:
"According to three people familiar with the sequence of events, several senior engineers on Mansfield's team vociferously complained to Cook about reporting to his replacement, Dan Riccio, who they felt was unprepared for the magnitude of the role," authors Brad Stone, Adam Satariano and Peter Burrows wrote. "In response, Cook approached Mansfield and offered him an exorbitant package of cash and stock worth around $2 million a month to stay on at Apple as an adviser and help manage the hardware engineering team."
