Teachers’ unions in cities throughout the country joined with socialist organizations to demand more funding for government schools and an end to “systemic racism” before they agree to in-school instruction.

The groups dubbed Monday a “National Day of Resistance,” as they demonstrated in cities such as Chicago, New York, and Los Angeles.

“I think that the Black Lives Matter [movement], in conjunction with the pandemic, it kind of illuminated all of the inequalities that take place in the black community with all of the lack of resources, the disinvestment in communities of color,” Nina Hike, a high school chemistry teacher in Chicago, said, according to NBC News.

“And then, now just the lack of resources even to get [an] education,” she added. “Nothing about being in a pandemic is normal. Nothing about dealing with racism is normal.”

The unions and social justice groups created a list of “demands” they say must be met for them to return to in-school instruction:

“We have a duty to be anti-racist educators,” Cecily Myart-Cruz, president of United Teachers Los Angeles, said, according to NBC News.

“Everywhere there’s systemic, structural, institutional racism, it’s our job to root it out from its very foundations,” she continued. “That means looking at the institutions, programs and policies to really break those, those barriers down. Our students are asking for that and it is incumbent upon us to do that work.”
