Recently a co-worker of mine was given a Senior Recruiter position back in November 2013. This person promoted is a recruiter that has always been very rude to me and we never really got along so I never reached out to him as all recruiters work remotely. Once promoted to my new manager he has been bullying me at work and making comments to me about finding a new job and maybe this is not for me. On the back end of this I am the top performing recruiter on the team next to this recruiter. As of Friday he put me on a PIP, but I don't agree with how I can be on it when I am the top recruiter for the team. How do I respond to this PIP?
