[I2S1] DD: Kill your manager to become the new manager as is the custom.
You need some fresh blood in order to make tracks across your next destinations, so you go ahead and put your manager out of your shared misery.
Now THAT'S proper insubordination.
Things remain stable, so this doesn't seem to be breaking any major internal rules. (If you'd ever experienced a hard day's work in the service industry, you would know this to be a pretty common idea.)
