Bottom to top:
-Governing Body incl. zone overseers, service, writing, etc commitee members
-Given ones/Bethel Heavies
-District Overseer
-Circuit Overseer
-City Overseer (though only good on paper)
-PO
-The rest of the service committee
-WT Conductor, TMS Overseer, Bookstudy Overseer
-The elders without one of the above assignments
-MS
-Pioneers
-Aux Pioneers
-Strong Publishers
-Misses a few meetings here and there publishers
-Inactive publishers
-DF/DA
Then of course there are subcategories to many of the above. If you are an elder, member of the Service committee and a bethelite or pioneer then your "stock" goes up. If you are an MS and also a bethelite or pioneer then in some cases you may be even more "famous" then some elders without one of the big assignments. Anymore you can think of?
For a religion that touts itself to be fully christian,clergy class free and non discriminatory they sure do like to categorize people. Its quite an oppressive social structure in the WT and its all based on working or your salvation despite the bible saying that life is a "gift from god"
