"First Team" Principle: Leaders' loyalty to their peers over their reports

when I asked for his support around difficult prioritization discussions, his response was “I believe in the Team First mentality, and our success is not necessarily putting my team nor our customer first- it’s in putting my peers’ needs first. Do whatever it takes to make them successful.”

On one hand I could see how this can theoretically lead to good outcomes all around… on the other, is this a joke? I hope to god this mantra doesn’t catch on, because what is a boss if he is not there to support you.
