The following are not single words, but phrases I hear (or have heard) in business settings that I dislike very much. I work in management consulting, so I hear these sorts of things more than I would like.
Hearing someone's "take" on a subject
Describing being unreachable as "out of pocket" -- where did this come from and why in the world is it used?
"Reach out to so-and-so", meaning to contact someone
"Getting calibrated" meaning, I suppose, reaching a mutual agreement or understanding of some sort
"Giving back to the community" -- meaning volunteering or donating one's time or resources -- more or less, doing anything more than lifting a finger to help further some social or community goal. I agree with the spirit of "giving back" completely, but the phrase implies, to me, that something has been taken away in the first place, which may not be a good thing
Describing someone or something as the "real deal", meaning that it is authentic or genuine in some way
"The 800 pound gorilla" and "the elephant in the room", which I hear A LOT from television commentators or pundits, not so much in the business world. These would be fine with me if they were not such overused cliches.
I could go on. I could probably think of dozens more if given enough time.
