Randi Weingarten, president of the nation’s second-largest teachers’ union, plans to call on Thursday for a full reopening of the nation’s schools for the next academic year, saying: “There is no doubt: Schools must be open. In person. Five days a week.”

Her prepared remarks, made available to The New York Times, come with about half of the nation’s public schools not offering five days per week of in-person learning to all students and with many families uncertain about whether they will have the option for a more traditional schedule in the fall.

It had been weeks since Acy Grayson III, owner of Let It Shine, a home improvement outfit he runs out of his own home in the suburbs of Cleveland, had vowed to get a Covid-19 vaccine.

Appointments were available.

But Mr. Grayson, who never knows how long a job will take or when a new one will come along, had found it hard to commit to a time and a place. The mass vaccination site where appointments were not required was off his beaten path. He did not know that a nearby church, Lee Road Baptist, had been dispensing vaccines on Fridays — but the truth is, even if he had, it is unlikely he would have made the short trek to get one there, either.
