It will depend on the conditions of tenure of the Bethalites within a particular country - as it pertains to that nations Labour Laws.
So if JW had to "employ" the Bethalites then they would more than likely be bound to specific legislation related to a "Retrenchment process" *- which should include a pay-out, and also the Bethalites should have been part of an Unemployment Insurance Fund which will allow you to draw a payment from the labour office for a certain very short period.
* Generally this 'process" [yes its a process] cant take place overnight or even in a very short period of time. Its cannot be a unilateral process either and extensive negotiation has to take place involving all parties concerned.
I would be interested to know the process that these Bethalites faced in various parts of the world. I feel that I stand to be shocked !
