In the Beginning there were HumansI recall my first few jobs at both major corporations and at startups, there was always a HR person I could reach on the phone, or simply walk over to their office to get small and big matters resolved. HR personnel where typically visible and accessible. Human Resources representatives interacted at a personal level with employees and often knew you on a first name basis.
It seems with more technology that HR has lost its human to human interaction and become more impersonal and mechanical. Today, if you need some payroll or benefits issue resolved, you typically need to submit a "ticket" in some online system and wait for someone (you have never met) to contact you back over email or if you are luck over the phone. Or if you are lucky you can click your way through a labyrinth of HR GUI applications to find what you need.
