I've worked alongside some of the sketchiest of IT contracting firms and I've seen this kind of behavior. One firm just decided to replace the trained contractors working on my BI team with a bunch of junior devs overnight, no explanation, no warning. The fact that BI management kept employing them says more for the suspected "hello money" I think was paid to get them in first.
