Chicago Mayor Lori Lightfoot thinks the city’s schools should be ready to reopen in the fall, but the Chicago Teachers Union isn’t so sure.

Lightfoot told reporters at a press conference on Friday that city officials are considering “different options” for restarting in-school classes, and Chicago Public Schools CEO Janice Jackson told parents in an email the hope is schools “open on time and at full capacity” in the fall, Block Club Chicago reports.

The Chicago Teachers Union, meanwhile, is leveraging the pandemic to force city officials back to the collective bargaining table. CTU officials announced plans to demand smaller class sizes, sanitation stations, and increased cleaning staff, among other changes. Last October, the CTU led a teachers strike that lasted for 11 days before the union got the contract terms it wanted.

“Everything that I am hearing from medical professionals throughout the world is that there are going to be intermittent outbreaks, so to act like … this world is going to return to a normal that people are used to is dangerous,” CTU Vice President Stacy Davis Gates told the Chicago Tribune. “There has to be complete and total recognition of what we’re dealing with.”

CTU President Jesse Sharkey described talk about reopening schools as “foolish.”

“The idea that we are going to open school in the fall when you haven’t even figured out how to get internet access to the students that you’re dealing with now … those are the necessary components for returning to school that we know are going to be part of any plan that’s going to work,” he said. “… If someone’s positive at a school, you’ve got to close it because it means everyone who was exposed to them could potentially be positive and you’re not going to know for two weeks.”

Regardless, Lightfoot contends CPS officials could make changes to mitigate the risks, such as “having alternative days. Kind of a platoon circumstance. Really limiting the number of kids that are in a classroom at any given time,” Block Club Chicago reports.

“We’re looking at a range of different options,” she said.

“Of course, it’s going to be guided by science; it’s going to be based upon feedback from the entire school community, which of course includes teachers,” Lightfoot said.

Reopening Chicago schools is part of Lightfoot’s five-phase plan for reopening the city after weeks in lockdown due to the coronavirus. That plan is informed by a similar five-phase plan unveiled by Gov. Jay Pritzker last week, dubbed “Restore Illinois,” according to the Tribune.

“Restore Illinois … indicates the earliest the state’s schools could open is during phase four, at which point gatherings of 50 people or fewer will be allowed and schools may reopen with social distancing policies and safety guidance from the Illinois Department of Public Health,” the news site reports.

“When the Chicago region will reach phase four, and whether that will be by the traditional start of the school year, will depend on a continual decline in the positivity rate among those tested and in the number of patients admitted to the hospital. Even with loosened restrictions, face coverings and social distancing are still expected to remain the norm, officials said.”

The debate about reopening Chicago schools comes as President Donald Trump is urging the nation’s governors to “seriously consider” reopening schools as soon as possible, while the National Education Association, the nation’s largest teachers union, is urging leaders to ignore the president’s advice.

“We are listening to the health experts and educators on how and when to reopen schools – no the whims of Donald Trump,” NEA President Lily Eskelsen Garcia said. “ … Bringing thousands of children together in school buildings without proper testing, tracing, and social isolation is dangerous and could cost lives.”
