I think painting the contrast:

"kick ass and take names" route vs. the "tread carefully and make sure everyone likes you"

combined with the wrecking ball idea just paints a picture of someone who is grinding to get their work done but not worried about their relationships with or the collateral damage they cause for their coworkers. Reading your other comments I don't think it was your intent, just the way it came off to me at first blush.
