NEW YORK – New York City’s United Federation of Teachers union wants to kick charter schools out of public buildings they share with traditional public schools.

Parents apparently want the UFT and its supporters to leave the city’s charter schools alone.

Charter school parents and advocates associated with the group “Families for Excellent Schools” made their voices heard this week when they protested at New York City Hall, the Epoch Times reports.

Specifically, Families for Excellent Schools is taking issue with two lawsuits aimed at limiting charter growth in the city: a UFT lawsuit filed in July and another filed by union-friendly city council members in December to halt co-locations approved by Mayor Michael Bloomberg’s administration.

Co-locations allow charter schools to use unoccupied space in traditional public school buildings. The policy makes total sense, since charters are public schools.

“Our families need more quality education options, not less. Our school is primarily minority families that can’t afford another option,” Girl Prep Bronx parent Yvonne Guillen told the news site.

The city’s charter school parents are likely upset because most understand the union-led opposition to charters has nothing to do with student learning, or improving education. The unions hate charters because most of them employ non-union employees.

“According to the New York City Charter School Center only 10 percent of New York City charter schools employ unionized teachers, compared to traditional public schools, which only employ unionized teachers,” the Epoch Times reports.

In other words, the more charter schools expand, the more likely the union’s membership will shrink. With fewer members the union receives less dues revenue. Charter schools threaten the UFT’s bottom line, and the union is doing whatever it can to limit their influence, even if that costs children some quality educational opportunities.

That’s the primary reason the UFT backed newly elected Mayor Bill de Blasio, who has made it his mission to prevent charters from expanding, and vowed to require co-locating charters to pay rent to the city.

The union’s lawsuit, filed in New York State Supreme Court July 18, makes it clear the UFT is banking on de Blasio to undo Bloomberg’s progress with expanding charter schools in New York City.

“The proposals at issue here would bind the next mayoral administration to the same controversial education policies that the current administration has embraced,” the UFT lawsuit states, referring to 42 charter co-locations approved in October by Bloomberg’s Panel for Educational Policy.

“It is the height of hubris to suppose that future elected administrations cannot appropriately govern the NYC school system. The BOE’s attempt to concretize the policies of its current leadership is as transparent as it is illegal,” the lawsuit reads, according to the Epoch Times.

Throughout the UFT’s war against charters, union officials have repeatedly implied charter co-locations stem from some sort of dubious political agenda.

Thankfully, Families for Excellent Schools isn’t blinded by the union’s hypocrisy.
