PPOTUS Biden issued an Executive Order requiring that all businesses over 100 employees must vaccinate their employees.
Most prudent people believe that Biden's edict is Executive Branch over-reach but Biden's handlers are betting that corporations will put pressure on employees regardless of how events play out in court. The realities of the time required to get people vaccinated and the time to chase issues through courts really does not give corporations time to dally, a fact that PPOTUS Biden is counting on.
We don't have to play this out completely in our heads. Some hospitals are already doing this and they have already had some percentage of their workforce quit. Other workers, who consulted with attorneys, are not going to make it easy for the hospitals. They are going to force the hospitals to fire them and to generate cubic meters of paperwork. Any discrepancies in that paperwork makes the hospital liable for financial settlements at a later date.
My crystal ball tells me that truck drivers are the group that will bring the economy to their knees. Truck drivers are one of the single biggest occupational groups in the US with 3.5 million people engaged in that occupation.
Statistics are difficult to find but one statistic is that 97% of the trucking firms have twenty-or-fewer "trucks". Those companies are almost assuredly below the 100 employee cut-off and will not be impacted.
However, on the basis of actual tonnage moved, it seems likely that the market is dominated by firms over 100 employees. The trucking industry has been consolidating as government regulations squeeze firms. The overhead associated with documenting "compliance" is cheaper, on a per-per-ton-shipped basis, when it is amortized over the hundreds or thousands of trucks of a large firm than the twosie-threesies of mom-and-pop firms.
My impression of truck drivers is that they will tell their employers to pound-sand if Human Resources attempts to pressure them to get vaccinated against their will. They know that there are a butt-load of smaller firms out there that are hiring.
Factories will be impacted in hours as JIT inventory levels are depleted and they run out of places to store finished goods. Trucks don't just deliver parts, they haul away finished goods.
Grocery and liquor/beer stores would be impacted in a matter of hours or days. So will gas stations.
Drug stores might be able to hold out for days or weeks.
Garbage collection will start to impact quality of life in weeks and months.
If you are going to play chicken then you need to be aware that there are people out there who subscribe to a different form of "rational" than you subscribe to.
Truck drivers are rational, but in a different way than Ivy-League graduates. A fact that is about to spank our would-be-rulers if they don't pull their heads out of their nethermost regions.
