Office and factory workers of a suddenly-derelict company can walk off the premises and go home. Imagine finding out that not only will the paychecks stop, you also can't leave your desk.
Obviously not ideal, but at least you get fed and eventually get back home.
On the other hand, unlike factory workers in a totally bankrupt organization, the ship crews will get paid - they get "priority" on the ship and cargo; if the ship gets sold in some auction or restructuring, the new owner can't take possession until the previous crew gets paid.
1: "I need water"
2: "Don't worry, next year you'll (probably) have enough money to buy some"
Surely there are international agreements with remedies for such situations? When do the coastguard step in and save the crew from dehydration/starvation?
But am not aware of reports about how things are for them this week.
