Jellyfish Backbone 

Jellyfish backbone is a person who says one thing but does the opposite and blames others.

My boss has a Jellyfish backbone.
She speaks of standards and holding employees accountable for results. But, every time she has the chance to prove her statement she makes excuses and does nothing.
