Cons are many.
Weak HR leadership lacks the spine to do the right things. Vindictive people who will not bat an eye lid before deciding to demean the efforts of anyone who has decided to part ways with the organization.
Leveraging core competencies of people isn't what the HR team does. Work allocation is pathetic. No one really has a clue as to what they are doing or what is it that they are trying to achieve.
Good people prefer leaving the organization to sticking around and ruining their careers as is evidenced by the number of attrition that is seen in the HR team in the last few months.
