IT Professional Salaries

Question reguarding the ?IT professional Salaries? doc. I downloaded the document ?IT professionals Salaries? and handed it over to my boss to review (I am constantly fighting my boses for we get paid too little) and he wanted to know the basic description of the jobs (being picky). Is there any information that I can hand him reguarding this? I would greatly appreciate it. The ones I directed closest to our job were: PC Work Station Manager,Data Center Manager,PC Applications Specialist,and Quality Assurance Analyst (all on the SE region?Ga.).
