I am willing to say yes they can't sustain this long term. They already have a shortage of nurses before they started the mandates. Pulling a NG nurse from a civilian job to cover another civilian job is not sustainable.
They are resorting to paying double the money for retired nurses to come back, and also importing Filipino nurses.
The end is near.
They will try to use OSHA to backdoor through their mandate. But for OSHA to do it at this point so quickly they have to prove there is an extreme danger of potential death from"covid19" for most people.
In reality vast majority of people can survive "covid19" and thus when OSHA decides to put it up it will be quickly challenged.
Many of the people in the NG have civilian jobs. You pull them from their own civilian jobs to cover other civilian jobs still creates a shortage.
The strategy is simple it is a game of chicken and they can't sustain this long term.
For the UN to mobilize it would take half a year. FEMA for example can't mobilize within a month of a hurricane disaster. Living in Florida we know for a fact that FEMA isn't going to "help" within a month. So we plan accordingly to be self sufficient in the case of a disaster. Federal government may wield some power but it is still a cumbersome giant in the grand scheme of things.
The US military is the only one with the proper logistics to mobilize within a month and even then it takes time if we are talking about a nationwide effort.
For a job linked to federal contracts/money consult with an attorney or lawyer. If not then the only way for the mandate to apply to employees in the state of the Texas is to backdoor it through OSHA. But once OSHA puts it up they will be immediately challenged from every direction imaginable.
Basically it is going to be chaotic.
So terrible.
