If I were you I would worry a lot less about why your posts on a layoff board are being deleted and a lot more about the EEOC enabling companies to test and vaccinate you like you are livestock.
I have no direct information from anyone at COP that this is in the immediate future but you need to think about where you draw your line before it is crossed.
Have respect for yourself. Object. Refuse. Don’t let anyone treat you like property.
