I've been working for my current company who specializes in HR software for about 6 years now and from what i see both introspectively and from our clients, most communication issues are a result of a poor corporate structure and/or culture. Having a HR person/psychologist will likely only address the symptoms rather than the problem itself. But i do totally see where you're coming from. I did a bit of side-study into psychology and it seems like business execs could benefit hugely from involving dedicated Psychologists into business decision making (including HR).
