Mostly cons is a resource management practice. Unfortunately, relationship with RM will influence at all your working aspects at company. I would say that company splits in parts by resource managements pools and each pool represent separate small company. So, unfortunately, I have to leave from company due to misunderstanding and accumulated contradictions with my RM. Generally, I'm leaving not from company, but from my RM. As I said, I believe that RM practice must to be reformed.
