Fisherman in the two congregations I attended I rarely heard of any announcement of an elder ceasing to be an elder, but when I did hear of such I did not assume the worst. I knew that people could loose interest in being a elder, or a ministerial servant, just as they could loose interest in being a regular pioneer.
I had quit being a regular pioneer due to burn out and due to never enjoying spending so much time and effort in field service, and because of desiring to pursue a better career. I had gone to college to get a great career and had completed college (and obtained a Bachelor of Science degree in Business Administration) three months after I had become a regular pioneer, but was only working part-time because of the hours requirement (90 hours per month or 1000 hours per year, of field service time, not to mention the time preparing for return visits and talking points to be used in the field) of regular pioneering. After being a pioneer after nearly 3 full years, for a month or two a number of people in my congregation said things to me indicating they thought I was still a pioneer. I thus felt compelled to tell them I had quit. An announcement during the meetings was never made to the congregation that I was no longer a pioneer. I wondered why it wasn't, since i thought such announcements did not necessarily mean the former pioneer had done something wrong. I had thought that such announcements were required to be made when a person ceased being a regular pioneer, for any reason (not just for doing something bad or for not meeting the requirements). I had wished that such an announcement had been made about me, so I wouldn't have to tell people week after week that I quit being a regular pioneer. When I told people that I quit being a regular pioneer they looked sad, but that puzzled me because I had never intended to be a regular pioneer for the rest of my life. But in hindsight, I guess if an announcement had been made, then many people would ask me why I am no longer a pioneer and I would have felt compelled to tell them that I had quit, so they would know I had not been removed as a pioneer and had not become disqualified to be a pioneer.
Multiple times during the years I was a ministerial servant I had thought of resigning as a ministerial servant. Multiple times I even considered resigning as a ministerial servant by me making an announcement from the platform of the kingdom hall (at a time when I was assigned by an elder to give announcements he had written down) that I was no longer a ministerial servant (and possibly also saying I had resigned). One reason I thought of doing such (in the congregation of which I was first a ministerial servant) was because an elder had announced to the congregation I had become a ministerial servant, even though prior to that I had not been informed I was chosen to be a ministerial servant or even asked if I wanted to be one. I had wished they had asked me first and I had resented that they hadn't. [In the second congregation I attended I was asked first and I accepted it, but multiple times I later thought of quitting being one in that congregation also. Eventually I did cease being one.] I had also thought that if in my first congregation if an elder would complain of me quitting that way with me making an announcement of such without the approval of the elders, then I would reply: "Well, I was appointed as a ministerial servant without my pre-approval and it was announced that I was a ministerial servant without me ever being informed that such would be announced, thus I thought I would quit without telling the elders of my intention and announce it without their approval". However I never did make such an announcement and never did quit being a ministerial servant at that first congregation, though obviously I ceased being one there after I moved to a second congregation.
Readers, regarding Raymond Franz becoming disfellowshipped and the circumstances of such, if I recall correctly from reading his autobiography, the process of him being investigated by the WT headquarters for possible disfellowshipping started soon after the following. In the congregation Franz was attending the elder body had decided to appoint Franz as an elder and had submitted their recommendation. The governing body of the WT strongly disliked that and thus sought some grounds to prevent such and to oust Franz from the WT's JW religion. The WT soon adopted a policy that if a JW eats a meal with a person who disassociated himself/herself from being a JW then the JW eating with such a person would be subject to disfellowshipping (if unrepentant of eating with the officially ex-JW).
As a side note, yesterday a JW woman (whose voice sounded like that of an elderly person), attending a kingdom hall of the territory of which my home is located in, called me to engage in witnessing (about the topic of "does God answer prayers"). I told her I am an inactive JW who wishes to remain inactive (and I mentioned the name of the congregation I last attended). I also told her "but I wish you a great day".
