The news: Coronavirus infections in the US are on the rise in every state because of the highly contagious Delta variant—just as companies are returning employees to in-person work. Big Tech companies are being forced to reassess back-to-office timeframes as well as whether to impose vaccination and mask policies, per Mashable.

How we got here: As the nation’s vaccination rates plateau, the sudden and sustained spread of COVID-19 variants has resulted in surging infections in every state.

• The Delta variant can be transmitted within 5 minutes of contact with a contagious person, while the older variant was transmittable within 15 minutes of contact according to Dr. Linsey Marr, an expert in airborne transmission of viruses.
• Overall new cases in the US have increased 141% in the past two weeks.
• The CDC is once again urging all people to wear masks indoors, regardless of vaccination status.

The bigger picture: Businesses have looked to Big Tech companies as models for implementing remote and hybrid work during the pandemic, and have largely followed their lead on return-to-office policies. These policies have been a source of tension between employers’ desire to return staff to the office, and employees’ preference to remain remote. Meanwhile, many tech workers looking to change jobs are seeking more flexibility around remote work per Fast Company.

• Twitter closed its San Francisco and New York offices due to the current surge. The company announced Wednesday that they are pausing future office reopenings after considering CDC guidelines.
• Google on Wednesday also announced that it will delay its office returns to October, a month later than originally planned. Apple is similarly pushing back its return-to-office deadline to October and is requiring masks for employees and customers of its retail stores.
• Google and Facebook will mandate vaccines for all employees at their US offices and expect to require vaccinations in other locations. "Getting vaccinated is one of the most important ways to keep ourselves and our communities healthy in the months ahead," Google CEO Sundar Pichai wrote in a blog post.
• Amazon is not requiring employees to be vaccinated and only enforces mask-wearing for unvaccinated workers.

The dilemma: Big Tech companies who were looking at returning to work by September are scrambling plans made before the sudden surge of the highly contagious Delta variant. The unpredictable nature of coronavirus variants and increased rates of infection will continue to confound businesses as they struggle to remain profitable while keeping employees and customers safe.
