Many years ago, I had a really bad attitude. I was lazy and resentful. Flippant and disrespectful. My boss was my friend and over beers he told me to straighten my ass out. I didn't. He put me on and EIP and I realized I had wandered too far. That was my wake up call and I straightened my attitude out. It was embarrassing but it worked for me.
OTOH I have seen it misused too, but not on me.
