The Society is very relaxed about JWs receiving welfare - all they are really bothered about is that JWs do as much ministry as possible.
I remember a congregation I was in where the meeting for field service was scheduled for a later time (10.30am) on a Tuesday morning because that's when many of the pioneers had to "sign on" ( in the UK unemployed people usually have to turn up at an unemployment centre early in the morning once a week or fortnight to confirm that they are still unemployed ).
Another pioneer deliberately only worked 16 hours a week cleaning windows to maximise his benefits and time on the ministry. ( This is very common in the truth- in the UK parents with children get tax credits and other benefits. )
I remember my father being very annoyed when another elder was speaking about how he only paid one pound a month rental for his house ( he claimed housing benefit ) whereas we lived in an inferior house and he was having to pay a large mortgage and work full time.
You won't see it in print for obvious reasons but the official Society line is that JWs should claim for whatever they can. To illustrate , when I was an elder , we wondered about appointing a brother to be a ministerial servant who had 4 kids , neither he or his wife worked ( they were both healthy - just lazy and enjoying a rent free , council tax free and heavily subsidised life ) and they aux pioneered a few months a year. Some of us on the body were unhappy , arguing that the bible principle "If a man wants to eat , he should work" should apply , so we decided to discuss it with the CO. When the CO came , he said the the Society had no problem with appointing brothers on benefits and that there was no objection whatsoever to the appointment.
