I'm gonna be the devils advocate here: If someone in HR can save a company hundreds of thousands, if not millions of dollars by removing underperforming workers, and replacing them with better workers, shouldn't that warrant some bonus? In the same way that if some engineer discovers a bug that is costing the company a lot of money, and fixing it, should also get a bonus?
