ExBethelite: what I can tell you is that there is a rapidly declining number of brothers who want to reach out as it’s called.
Yes, though I'm not an elder, I've seen this too. There are several congregations I know of where there are a number of brothers who are old enough and experienced enough but they are not being 'promoted'. With some it is due to health, but with others they have probably refused to take on more, while a few I know have 'issues' that prevent them from being considered. Some of them might be playing their health or other issues up to prevent being asked to do more, and I wouldn't blame them.
I was never interested in being an elder. Back when I was more naive about what went on in the org, it was because I didn't think I had what it takes to handle judicial cases and didn't want to have that kind of (spiritual) "life or death" pressure on me. And now I know even more about what goes on, I certainly wouldn't want to be an elder, knowing the burden the org puts on you, and also the internal politics and strife within bodies of elders.
Indeed, if I were in the position to be first offered MS now, I would probably decline that too. Back when I was made MS it seemed a more worthwhile role. We had a 'real' theocratic school and a service meeting with parts that were worth preparing and getting on the platform for. Ministry was still focused on developing some sort of art of teaching and seemed more substantial. I actually used to enjoy giving the old "number 4" talks, bible highlights and Q&A service meeting items from the OKM, taking midweek field service when few elders were available, supporting them with groups at weekends and going with them on a few shepherding calls.
Now the role of a MS on the platform is often just to top and tail a video. Even a lot of the elders' items are the same, such as playing the silhouette ministry videos or introducing the GB updates. And ministry is often a much smaller group who split up straight after the prayer, with some going to do a few doors by themselves and others going to a cafe to write letters (allegedly) or staying online.
but there is such a shortage now sometimes sister are doing microphones
I know of several congregations that since the return from the pandemic, have started using sisters on the audio-visual desk during the meeting, due to not having enough brothers to do all the talks as well as handle the platform, mics and sound. I can't ever remember seeing that before.
there is not enough brothers to do all the jobs and they are not getting done well
I've also noticed this too. Several in the congregation are noticing that elders are not as visible on shepherding visits or out on service with the rest of the congregation as they used to be before the pandemic, and will comment (privately) about it. A number of elders themselves that I've spoken to sound tired and overwhelmed and are aware things are not as smooth as they were, and that's just what they're prepared to say in my company. I can imagine their meetings with each other and the CO are probably even more depressing!
