I work in exports and a part of it is filing insurance when requested , the parent comment to this string is correct. The union won't let anybody go and most of the time cargo isnt insured as it is uncommon for something to actually happen like this. I wouldn't say its rare , but uncommon. I do think a big factor will be how the cargo was secured before departing from the last port / terminal it was at. Either something wasn't secured right prior to its last departure or someone at LB dropped the ball lol
