Labor Categories are a necessary evil in most companies, and the are probably standardized across the entire firm, even though what Office A does has little in common with what Office B does.
I don't dislike Labor Categories, as they have little to no bearing on what we do or how we operate.
What I DO dislike is how labor categories are used withing our vacancy announcement system.
The company's "boilerplate" labor cetegory description has so much BS that it's meaningless. I do have the opportunity to add "position specific" test, but this appears at the end of a very long paragraph, with no separation or distinction. A candidate needs to read all they way through physical fitness and "lifting" requirements before they can see if I'm seekin an ME, a EE, or a software engineer (in the case of the various engineering categories).
