Sounds like my company:

X = Supervisors/Managers and above
Y = Tech support (my area), the "white people" would be the NOC (large business tech support)
W = customer care, which is outsourced.
B = Network techs.
You get the picture.

Luckily X and Y are all there for each other and are pretty closely knit. I really hope you get out of this mess soon and hopefully into a more supportive environment.
