Already, Twitter late Wednesday announced it would close its offices in New York and San Francisco after just re-opening them two weeks prior. Lyft, meanwhile, announced it would push its office re-opening all the way out to February.
Compulsory masking might just make a re-appearance, too, with California saying it would push for people to be masked indoors regardless of their vaccination status.
The measures bring much of the country's march back to normal in the wake of above a year of restrictions to a slowdown as the particularly virulent Delta variant is thought by experts to be a major threat - especially to the unvaccinated.
Over the past month, the average new daily cases across the US have increased by 376 percent, from 11,887 on June 26 to 63,248 on Tuesday, for instance.
Deaths however, have remained flat with 406 recorded on Tuesday amid a seven-day rolling average of 290.
Still, companies appear to be acting as though things could deteriorate once again.
California Governor Gavin Newsom gave 249,000 state workers until August 9 to get the vaccine or get tested weekly.
In New York state, all 250,000 government workers will have to get the COVID vaccine, or partake in mandatory weekly testing, Gov. Andrew Cuomo said Wednesday. Frontline workers at hospitals will have no opt-out option.
Cuomo said he encouraged private businesses to require the vaccine, too -- not just for employees, but also for customers.
He asked for employers to call their workers back by Labor Day, Sept. 6, and predicted that a call paired with a vaccine requirement would help get the economy back to normal.
Private businesses across the country appear to be making the same calculations, with many saying they'll require vaccinations for workers to return to the office.
Facebook announced it would leave room for exceptions and different situations in its vaccine requirement.
'How we implement this policy will depend on local conditions and regulations. We will have a process for those who cannot be vaccinated for medical or other reasons and will be evaluating our approach in other regions as the situation evolves,' Lori Goler, Facebook's vice president of people, wrote in a statement on Wednesday afternoon.
Around half of the social media platform's 58,000 employees are expected to be working remotely when the offices open in October.
The date was delayed by a month due to the surge in cases nationwide fueled by the Indian Delta variant, the company announced.
