This sort of treatment was the beginning of the end for me as a JW. My 20-year-old son, who was one of the very few of his generation to still be attending the KH, was removed from his privileges running the sound system because he failed to turn in 10 hours a month of field service.
He was turning in time every month, just not enough to satisfy these arbitrary requirements, requirements which were never stated up front when he began his duties. This young man was struggling with his attachment to the JW life but was sticking with it mostly because of his love for me.
The job at the KH gave him a connection to the org. and made him feel useful. When the ax-wielding elder told him that he was cut off from his job, he was hurt to the point that he no longer had any motivation to keep going. I remember telling that elder at the time that what he needed was a helping hand, not a shove out the door, but to no avail.
That's their sort of love, I guess.
Anyway, it all worked out in the long run because after my son left, I soon followed. Not the result they were expecting, I imagine.
