Maybe this is why Boeing has been rumored to be considering a 1 October plant halt across Boeing for at least 3 months?
More likely, lack of orders. B737-Max is still grounded; problems recently reported in other Boeing jet airliners; domestic and international air travel down...what? 80 - 85%?; thousands of airliners out of service/in storage; etc., etc.
Being furloughed (with partial pay?) at least means the company wants to keep its trained workforce together until manufacturing picks up again. The question is: what happens when those three months are over?
Of course, there is always the 1984-style perpetual conventional world war option. That solves a lot of manufacturing and employment problems. Problem is all the key players now have nukes. So keeping it strictly conventional could be tricky.
< /sarcasm> Just in case someone is a little slow on the uptake.
