I notice that in the recent Instructions for New Regular Pioneers (2020-08-S-236-E) it lists a number of assignments for which a pioneer can be credited (up to 75) hours in a month.
construction oversight, Assembly Hall oversight, assembly oversight, and convention oversight, as well as serving as temporary volunteers at Bethel, commuter Bethelites, remote volunteers, Bethel consultants, Hospital Liaison Committee members, Patient Visitation Group members, Disaster Relief Committee members, Local Design/Construction Department field representatives and maintenance trainers, and so forth. Approved assignments also include assisting with Kingdom Hall construction when such is done at the request of the branch office or its representatives overseeing the project, assisting with pre and post-assembly or convention work, assisting with work at Assembly Halls, conducting or participating in congregation meetings held in prison, as well as attendance at a theocratic school or class
When I was pioneering and doing pre and post-assembly work I was told I could include the time spent working in my monthly report, which I did. After all, it was all sacred service. However, I notice the instructions now given to pioneers is that they
should report this activity to the congregation in the 'Comments' section of your Field Service Report (S-4). The hours spent working on an approved assignment should not be combined with the hours spent in field service.you should keep a record of all the hours spent working on the assignment during the month. You should report this activity to the congregation in the “Comments” section of your Field Service Report (S-4). The hours spent working on an approved assignment should not be combined with the hours spent in field service. Although your theocratic assignment is part of your sacred service, some time should be spent in the ministry each month.
I occasionally read on this forum the suggestion that the amount of field service is exaggerated, so while I personally don't see this record keeping as a scriptural requirement I do applaud their transparency.
