So they do a variety of things:
- Attend Circuit Assemblies - so this might take around 10 to 15 weekends a year
- Attend a Special Assembly Day - so would take 1 weekend a year (they do not organize SAD but usually are the visiting speaker for one)
- Serve as Chairman at one or more District Conventions - this would take 2 weekends roughly
- After some Circuit Assemblies they serve with the CO the week following a Circuit Assembly for a workweek where they assist, formally shepherd, and complete a PQR report on the CO and his wife if he is married. The PQR is like an annual performance evaluation on an employee. It is used to determine if someone should stay in their assignment (are they still qualified) or if they should be removed or should go on to an assignment with more responsibility. This would be an additional 10 to 15 weekends a year.
- They do teach the School for Congregation Elders. Since these are mostly complete, some US DOs are going abroad to teach as well.
- Special projects for the Service Department/Governing Body/Branch Committee. DOs (and some experienced COs) work on special projects while in the field. Sometimes they work on these projects and do not serve congregations during particularly busy parts of the special project. An example of a special project might be a new procedure the branch office wants to get input on or have drafted, assist with other new organizational initiatives. In some cases, they return to the branch office temporarily to work on these.
- Special Committees - when a particularly nasty issue arises (especially where it is a judicial issue where more than one appointed man is involved) they might serve as the chairman of a branch-appointed special committee in the field. This might involve some weeks of time to handle.
- Regional Building Committees - each RBC is assigned to a DO who oversees it and performs an annual review with the committee, usually in the December - March timeframe.
You can see that all this fills a "service year" up pretty much. You might notice that you get a substitute DO more often than a sub CO. This is why, especially the special projects and special committees part of this.
Sorry if the post was too long. Just wanted to share what I know. I'm looking forward to your comments on all of this, some of which you may not have been aware of. Someone commented about DOs being "rock stars" - they are indeed very very powerful in the organization. If you hack one of them off, you can generally kiss your "spiritual career" goodbye.
