I doubt that he quit just because he was forced to go back to the office. He was probably unhappy there for multiple reasons. Keep in mind that he can get a job anywhere and probably will get better pay if he even needs to work ever again. So quitting is not a big deal for him. So keep that in mind to anyone thinking they can do the same. It also speaks to the fact that no one is irreplaceable.
