Over the last couple of years they have had remarkable success with the completely astounding incentive of dropping the hour requirement for auxiliary pioneering in March/April (or whenever). The organisation invents a job description which has absolutely no basis whatsoever in the scriptures, gives it an arbitrary hour requirement - 50 hours a month - and makes publishers sign a written agreement that they will meet this requirement.
Of course this is all done while insisting that it isn't done so that more people can wear the pioneer badge. In fact someone would be deeply offended if you were to tell them that!
I say, stop announcing the names of who is auxiliary pioneering each month, and watch what happens to the number of auxiliary pioneers.
