As new cases of COVID-19 driven by the delta variant sharply climb in the United States, multiple major companies are joining a growing list of employers that have delayed their return-to-office dates.
The U.S. Centers for Disease Control and Prevention listed the delta variant as a variant of concern in the U.S. and noted that it is substantially more transmissible than previous variants.
Companies are implementing vaccination mandates and reinstating preventative health measures such as mask-wearing indoors as cases, hospitalizations and deaths surge across the country.

All Blackrock employees based in the U.S. won’t be returning to the office until Oct. 1 at the earliest, according to a memo obtained by FOX TV Stations.
Only vaccinated individuals will be allowed in offices until the official October return date and masks must be worn indoors in the company’s Atlanta, San Francisco, Los Angeles and Washington, D.C. locations, the company said.
The company is also planning to provide updates on its "Future of Work" pilot program which allows a hybrid work week (three days in, two days flex) in September.
Google is delaying its return to office date from September to mid-October.
The company announced on July 28 that any Google employee coming to work on a Google campus "will need to be vaccinated."
"We’re rolling this policy out in the U.S. in the coming weeks and will expand to other regions in the coming months," Google CEO Sundar Pichai wrote in a blog post. "The implementation will vary according to local conditions and regulations, and will not apply until vaccines are widely available in your area."
Humana also plans to delay returning employees to the office at full capacity until Oct. 18., according to a company statement emailed to FOX TV Stations.
COVID-19 vaccines are not mandated but are "strongly" encouraged.
Uber Technologies Inc. is pushing back its back-to-office date to late October globally, and all employees in the U.S. will have to be fully vaccinated before returning to office, a spokesperson said on July 29.

Why is the delta variant a concern?
The delta variant has sent new U.S. cases surging to 94,000 a day on average, a level not seen since mid-February. Deaths per day have soared 75% in the past two weeks, climbing from an average of 244 to 426. The overall U.S. death toll stands at more than 614,000.
CDC data shows the primary delta variant, known as the lineage B1.617.2, makes up 83.4% of COVID-19 cases. But when combined with its sublineages, that number grows to 93.4%.
The AY.3 sublineage equals 9.1% of cases, the AY.2 makes up 0.8% and the AY.1 accounts for the remaining 0.1%.
The CDC calculated the numbers through its national genomic surveillance program, which is tasked with identifying new and emerging COVID-19 variants. Using data from genomic sequencing, the CDC groups sequences with similar genetic changes associated with important epidemiological and biological events into lineages.
New evidence from the CDC released on July 29 revealed that the delta variant can be as contagious as chickenpox. A surge in new cases being spurred on by the variant of concern has led the CDC and federal health officials to reverse their recommendations on mask-wearing indoors.
The CDC changed course on masks on July 27, recommending that even vaccinated people return to wearing facial coverings indoors in parts of the U.S. where the delta variant of the coronavirus is fueling infection surges.
Citing new information about the variant’s ability to spread among vaccinated people, the CDC also recommended indoor masks for all teachers, staff, students and visitors at schools nationwide, regardless of vaccination status.
The CDC noted that vaccinated people are 10 times less likely to get seriously sick from COVID-19, and three times less likely to get infected. The agency has stressed that unvaccinated people account for more than 99% of recent hospitalizations and deaths in data collected between January and June.
"Those at highest risk remain people who have not yet been vaccinated. Now is the time to get vaccinated. We know these vaccines are working and we know they save lives," Dr. Rochelle Walensky, director of the CDC, said during a White House COVID-19 press briefing on Thursday.
