I think this insanity may possibly explain why masking was mandated in the first place, as it puts the “unvaccinated” in the same precarious position as “Gomer Pyle” in Full Metal Jacket—i.e., as the one whose failings burden everybody else, so that everybody else will turn on him, and force him to “improve,” even though “improvement” = death.
Spoiler alert: Just as “Gomer Pyle” ends up blowing his own brains out, so would any worker pressured, by the others, to get “vaccinated” be potentially committing suicide.
