Don't they have to sign "vow of poverty" so the WBTS get charity status.
Not necessarily: the 501(c)3 Non-Profit status is not directly tied to the Vow of Poverty. WTS had the Non-Profit thing long before they went to VoP's. You can have a religious Non-Profit scenario without having unpaid volunteer work that would warrant the VoP's.
The VoP was done to keep the TaxMan from wandering around Bethel and asking to see the tax and pay records of these 1000's of bodies that MUST be making a pile of $$$'s.
As I recollect, the VoP requires a minimum stipend, set arbitrarily @ 100$/month or 1200$/year. Once this is all taken care of, filing the tax returns for a few thousand Bethelites was a piece of cake.
The Roman Catholic Church has had this practice in place for centuries; it simply got grafted into the US Codes to account for this anomaly in the economic capitalistic system. However, the RCC does customarily take in these people FOR LIFE, with no quibbling.
Once WTS discovered this, a major headache became explainable. It neatly tied up a loose end.
However, this may not have been thought out for a proper long term solution: Mary points out that Bethel has been promoted as a LIFETIME CAREER, IN WRITING. That's a loose end that amounts to the tail wagging the dog.
There were non-JW tenants in the building, who had a right to stay there under NYC tenant laws.
Eviction is not a snap-your-fingers, done-deal matter. This is one of a variety of legal situations that make eviction a slow process. And if you find a new wrinkle, Stays and Injunctions can freeze things the way they were for long periods of time.
And while DF'ing (a Church Law Tribunal matter) would change status of the original arrangement (Contract), that is not good enough to cross the actual Civil/Secular jurisdiction of Tenancy Laws.
