Many companies have adopted Biden’s mandate, with many telling workers that they would be fired if they did not comply. The CNBC survey finds a majority of U.S. CFOs (80%) saying they “totally support” the Biden administration’s mandate, while less than a quarter (15%) said they totally oppose it.

IBM told U.S. employees this week that they must be fully vaccinated by Dec. 8 or face an unpaid suspension.

“As a federal contractor, it is a business imperative for IBM to comply with this mandate,” the company said in a memo sent to employees this week. “In light of this requirement, the policies of many of our clients and partners, and the easy access to vaccines around the country, we will now require all IBM U.S. employees to be fully vaccinated by December 8, 2021, in order to work at IBM.”
