Startup Idea : Service to help people with HR issues at work

I've worked in the corporate world for the better part of 25 years and that problem I see over and over again is the average person doesn't have the knowledge to compete with issues that occur in the everyday work life with HR issues. The issues I refer to are warning letters, asking for a raise, complaints, termination etc. Your company has lawyers to help them negotiate what they can say and do, the average person working in these companies do not. Its an un fair playing field and I want to start a service to even the field. To provide guidance for the average Joe when dealing with these life changing situations, so he can have confidence when asking for the raise or responding to a warning letter. My service would be to understand the laws and industry rules and help people navigate within legal bounds. I want to provide different levels of support from an ongoing service which gives a certain amount of support on a regular basis to larger scale services as needed.
