The Merriam-Webster dictionary defines accountability thusly:
...the quality or state of being accountable, liable or answerable; especially : an obligation or willingness to accept responsibility or to account for one's actions <public officials lacking accountability>...
Not bad objectives for public institutions, but if you are a human being, specifically an employee, these are not terribly positive, empowering or motivating definitions. All of the responsibility devolves to them.
Perhaps that's why the "A" word has employees rolling their eyes, running for cover, or heading for the exit: many view accountability as just another modern, Newspeak business term for blaming, finger-pointing and butt-covering. Punishment, in other words.
