Life for the unvaccinated could get more difficult as bosses increasingly move to make COVID-19 vaccines mandatory.

The big picture: The Federal Government in May said that it is legal for companies to require employees to get vaccinated for coronavirus.

By the numbers: 64% of Americans said in June or July that they would support federal, state or local governments requiring everyone to get vaccinated, according to a survey conducted by The COVID States Project.

Our thought bubble, via Axios' Caitlin Owens: Many vaccinated Americans appear to be losing patience with people who are still unvaccinated, which will probably make them all the more tolerant of mandates.
