Not a typo, Stuart. Just Mexican :))
I guess what they mean is managers should not give special treatment to their direct reports or something like that. I cannot think of the appropriate word in English, but the meaning, in the context of a company, is very much like that of "paternalistic" as applied to governments:

A policy or practice of treating or governing people in a fatherly manner, especially by providing for their needs without giving them rights or responsibilities.

Hope this helps you get on the right track!

From the following sentence, this seems to be what it means here; however, from the definition of "apapacho", an "apapachador" would be someone who coddles employees (in this case some more than others). "Apapacho" literally means to cuddle, to caress, to treat gently.

Like my colleagues have already said, this is a very common word from Mexico. Indeed it means to show affection with love, hugs, kisses, caresses. In this case, it refers to overdoing it with compliments.
