I work in a field where my work must be reviewed by a more senior colleague. This colleague is not my direct line-manager.
On a number of occasions he has questioned my ability, and that of another team member to do the job effectively, and he has regularly threatened to speak with various team leaders and members of senior management to highlight my inadequacies. Admittedly I am not nearly as skilled as him, but I feel he is being overly harsh and that his threats are a form of harassment/bullying, causing me much anxiety.
After a several months of this treatment I snapped, and asked him to follow through on his threats and to speak with whomever he felt he needed to. As far as I know he did not, but since then our working relationship has worsened even further.
My only aim here is not to work with the person again, but there is currently no guarantee of this. The situation has not been resolved informally via the normal routes, and I now feel my only option is to raise this with HR. I am worried, however, that my perceived lack of skill will become the focus of any tribunal, and not his undermining constant criticism.
What are some pros and cons of escalating a personnel conflict issue to HR?
Just to clarify, I wrote this question in somewhat of a hurry. My term 'lack of skills' is incorrect, and has been prepended with perceived. I am not an under-performer by any means.
