When you say these words …….
Peer to peer – anything can happen. FIST may fly, vulgarities and 4 letters words may be audible.
Boss to subordinate – possible resignation or an “apple polishing” environment created. The “Yes Boss” culture thrives.
Subordinate to boss – definitely a career limiting move. Termination likely to take place. Must work for himself (no boss)
Conclusion …. best not to say it.
Use this as a joke instead.
Hope you are smiling …..
