About 1,200 Memphis school employees will see their wages increase to $15 per hour under a budget plan announced Tuesday evening.

The raises would would cost about $2.4 million, according to Lin Johnson, the district’s chief of finance.

The plan for Shelby County Schools, the city’s fifth largest employer, comes as the city prepares to mark the 50th anniversary of the assassination of Martin Luther King Jr., who had come to Memphis in 1968 to promote living wages.

Superintendent Dorsey Hopson read from King’s speech to sanitation workers 50 years and two days ago as they were on strike for fair wages:

“Do you know that most of the poor people in our country are working every day? They are making wages so low that they cannot begin to function in the mainstream of the economic life or our nation. They are making wages so low that they cannot begin to function in the mainstream of the economic life of our nation … And it is criminal to have people working on a full time basis and a full time job getting part time income.”

Hopson also cited a “striking” report that showed an increase in the percent of impoverished children in Shelby County. That report from the University of Memphis was commissioned by the National Civil Rights Museum to analyze poverty trends since King’s death.

“We think it’s very important because so many of our employees are actually parents of students in our district,” Hopson said.

The superintendent of Tennessee’s largest district frequently cites what he calls “suffocating poverty” for many of the students in Memphis public schools as a barrier to academic success.

Most of the employees currently making below $15 per hour are warehouse workers, teaching assistants, office assistants, and cafeteria workers, said Johnson.

The threshold of $15 per hour is what many advocates have pushed to increase the federal minimum wage. The living wage in Memphis, or amount that would enable families of one adult and one child to support themselves, is $21.90, according to a “living wage calculator” produced by a Massachusetts Institute of Technology professor.

Board members applauded the move Tuesday but urged Hopson to make sure those the district contracts out services to also pay their workers that same minimum wage.

“This is a bold step for us to move forward as a district,” said board chairwoman Shante Avant.
