More big companies are dropping vaccine requirement for workers

As some of the biggest U.S. employers lift mask mandates for vaccinated workers, other companies are going even further and discarding requirements that employees get their COVID-19 shots.

Germany's Adidas told its U.S. workers on Monday that it would no longer require they get vaccinated against the virus. 

"Though no longer required, we strongly encourage all employees to be vaccinated against COVID-19 and will continue to require all employees in the U.S. to submit their vaccination status by March 1," an Adidas spokesperson told CBS MoneyWatch in an email.
