I have no verification but based on what I've heard, in some rare cases people are "allowed" to leave their "assignments" to care for family needs and emergencies, but it is even more rare to be given any assistance, financial or otherwise to do so.
I have heard and seen recordings of talks given to Bethelites, asking them if it is Really Necessary to leave, if there are other family members, in the faith or not, whio can take on.the responsibility. They are encouraged to remain in the assignment at all costs. It is considered a "loving sacrifice" for family members to allow the Bethelite to remain there...
