I've seen elders and servants get counseled and threatened with deletion because someone in the family wasn't getting the congregation's averages in. I've known of ones that got axed because they "thought" differently than the rest. Their brains and mindset was not the same as the body's. I know of elders that LOOKED for anything they could find to strip a man of his duties. It's a big boy's club.
In congregations that I've been in:
One MS removed for low hours on his service report - never having been warned by the elders. The CO came in and removed him with no regard for the other exemplary qualities this man had.
One young man pretty much threatened with removal of mic carrying privilages because he played on a youth basketball team that had "Saint" on the jerseys (I can't reveal which school the "Saint" word preceded). This was because a sister was supposedly "stumbled" at the name on his jersey.
On MS removed because his daughter was df'd.*
*There are various reasons that I disagree with removal of brothers because of what their kids do. The simple fact is, most jw dads are not negligent. In effect, they are being blamed for actions that are not even theirs. It also puts tremendous pressure on their kids. Children who fall short of jw standards often blame themselves for their dad's loss of privilages. Is it wise to put that kind of pressure on a young person? When I was an elder, my daugher's behavior was exemplary, and still is. Yet, she felt a great amount of pressure, and told me so on several occasions. At times, she said, she just wanted to go out and "sin", maybe by smoking a cigarrette, just as a relief-valve so that people wouldn't think she was so "perfect" and so that she would no longer feel the need to be. Fortunately, she never 'acted out' in such a manner, but my guess is, had I remained an elder, she may very well have acted out before long.
