So CNN's 'theory' is that transport workers -- for some odd reason -- do not have access to the vaccines? Here's my theory: a significant chunk of the workforce doesn't want the vaccine to the point where they are willing to be terminated by their employer. Look around your place of work. If one-in-five workers got terminated next week, how would all the work get done. Most companies are already short-handed since last Spring when some state governments instituted lockdowns and the Feds decided to break the piggy bank with emergency UE benefits. But of course CNN can't admit to any of this.
the cargo/container ships are foreign workers, mostly slave labor from laos, cambodia, vietnam, china, etc. Out to sea for months at a time. But can’t get shore leave because they’re not vaccinated or have the wrong vaccine (i.e. sinovac) and so are subject to quarantine. Being ashore is when they can contact their families. What they’re asking for in a roundabout way is for ports to offer WHO-approved vaccines so by the next port, they can go ashore.
as to your empty workplace arguments, most small businesses have way less than 100 employees which is the rule, right? (or did they change it again?). As of today over 90% of Calif HCW are vaccinated; a quick look at NY hospitals and attrition is about 10% or less. American Airlines reported over 90%, United is over 99% vaccinated. US Military is 93% first shot. I dunno about other regions/businesses, but honestly, it’s easier to say I’ll quit to a survey or poll than to actually do it, especially with the holidays coming on. Probably easier if one is young and single and can move home in a pinch, or whose spouse is primary income anyway.
