I think OP is referring more to the sort of work culture associated with people who use language like that - bureaucratic, brown nosing, inefficient.

> "do the needful"

In my place, "do the needful" could mean you need to pay a bribe before they can do their job. Another way it's phrased is, "you know what to do."

Eh, in hindsight, maybe I should have left out that part since it detracts from my other point. It's just an aesthetic thing. For instance, I really don't like the word 'purposely'. I never saw it used before the internet came about, and 'purposefully' and 'on purpose' worked perfectly well for me. I'm sure it's correct, but it just rubs me the wrong way.
