Corporate email went out today: following CDC guidelines all US sites (we are a factory) may now allow fully vaccinated employees to work without a mask. Fully vaccinated is past the 2 weeks of either 2nd dose, or 2 weeks after J&J dose. All employees who wish to work unmasked must have their vaccination validated and will either be given a sticker for their badge, band or other identification that must be displayed at all times. Screening and social distancing will continue for all employees. Employees may also request a waiver, medical proof of inability to receive the vaccine required and will be determined on a case by case basis. i.e individual does not perform work that requires them to be within 6th of others.
I've already heard a whiner saying "I haven't gotten the vaccine, how is that fair"

Tomorrow, anyone who decided to receive the vaccine on site that was held, will be considered fully vaccinated. Everyone has had plenty opportunity at least at work, and no one was turned away.
The only part we are waiting on is how our plant chooses to validate eligible people.
Also they are assessing office workers coming back on a voluntary basis beginning in June.
