Omicron upends return to US schools and workplaces

Some school systems around the U.S. extended their holiday break Monday or switched back to online instruction because of the explosion in COVID-19 cases, while others pressed ahead with in-person classes amid a seemingly growing sense that Americans will have to learn to co-exist with the virus.

Caught between pleas from teachers fearful of infection and parents who want their children in class, school districts in cities such as New York, Milwaukee, Chicago, Detroit and beyond found themselves in a difficult position midway through the academic year because of the super-contagious omicron variant.

New York City, home of the nation’s largest school system, reopened classrooms to roughly 1 million students with a stockpile of take-home COVID-19 test kits and plans to double the number of random tests done in schools.

“We are going to be safe, and we will be open to educate our children,” newly sworn-in Mayor Eric Adams said on MSNBC.

New Yorker Trisha White said that she feels the risk is the same for her 9-year-old son in or out of school and that being with classmates is far better for him than remote learning.

“He could get the virus outside of school,” she said as she dropped the boy off. “So what can you do? You know, I wouldn’t blame the school system. They’re trying their best.”

While the teachers union had asked the mayor to postpone in-person learning for a week, city officials have long said that mask requirements, testing and other safety measures mean that children are safe in school. The city also has a vaccination mandate for employees.

New cases of COVID-19 in the city shot up from a daily average of about 17,000 in the week before the holidays to nearly 37,000 last week.
