O que significa Kiss up and kiss down?

I came across a random article on how to spot psychopaths around us especially in the work environment. As intriguing as that article sounds, what I'm interested in touching on this time is an expression that came up during my reading.

So imagine you are an employee in an organization and you obviously have to deal with different kinds of people. You see that depending on how much power or the position someone has in the company, their behavior might change. So suppose we are talking about a middle level employee that naturally deals with superiors and subordinates. You notice that this specific person at work praises or flatters his superiors so excessively it becomes embarrassing (in English we say they kiss up to their superiors), while treats his subordinates very poorly and with absolutely no respect. 

I didn't know that until I read the article, but there's a term, or more specifically a neologism, to describe that kind of situation: kiss up and kiss down. According to the article, "psychopaths and narcissists are extremely status conscious with a strong tendency to “kiss up and kick down.”

Hope you like today's expression. And always remember: stay away from people who kiss up and kiss down at work. I'll talk to you next time!
