I assume that your question comes from the understanding that living in this world, most jobs or responsibilities require us to report to someone in one way or another. The banker reports to his bank manager, the mailman reports to the postmaster, a soldier to his general, etc. This is the way the world runs so as to ensure quality control in all that we do.

But what about those responsibilities that we have to ourselves or to our families? Who ensures that we do a good job there? Are these responsibilities less important and therefore do not require quality control? Yes, there are government agencies that oversee these issues as well, but how much do they know of what is going on in my home or yours?

This is where religion and G‑d come into play. G‑d is the eye that sees all and the ear that hears all. He has instituted certain guidelines of morals and ethics that He requires us all to follow. Ultimately, we report to Him in this regard. When we say the Shema (lit. "hear"; the daily declaration of faith, recited in the morning and evening prayers and before retiring for the night) in the evening before retiring to bed we are giving Him a report of the day's events; what went well and what we will improve upon tomorrow. Ultimately, it is our faith in G‑d as the creator of the world and the Bestower of all good that keeps us in line.

So, as a response to your question: Yes there are junior rabbis who report to senior rabbis. In many cases there are regional directors within a given organization to whom local rabbis must answer. Ultimately, however, we all – rabbis and laymen alike, the people who administer faith and those who practice faith – report to the same place—the one G‑d who created the heavens and the earth.

All the best,
