How do the major activities and systems of HR workers (e.g., Strategic HR, Selection, Recruitment, Retention, Training, Performance Appraisals, Compensation, Benefits, Risk Management and Union/Management Relations) intersect with the major business systems of organizations (Marketing, Management, Accounting, Economics, Legal, Information Systems, International Business, the Quantitative areas, and the Finance area)?

Do they cross paths? How?

Are HR workers informed about other areas of the business? Cite the opinions of some experts (journals, etc.) who talk about the issue of how HR can be better integrated with the other actual business areas of an organization.

The answer should not consist solely of opinion statements, but be supported by factual information. As references, use articles and resources.
