True, however a lot of companies use the HR department as the evil arm. Top level management will always say things the workers want to hear but when it comes time for bonus or increment or adjustment, its the HR department that does the dirty job of under cutting the employees. Its a smart strategy, management will always smile and say nice things but when it comes time to talk about money, HR is the one that does the dirty job. In fact, in some companies the KPI of HR executives are how well they can squeeze the employee.
