"The one thing I do know is the work that she did is fluid. It has not stopped," said the Milpitas woman, who often traveled with Dukes when she was working on the case. "She was one of many voices fighting for the same cause."
An ordained minister, Dukes' faith was the foundation for everything she did, including taking on the retail giant, Roland said.
"She believed in helping people," Roland said.
In her off time, Dukes helped organize community banquets with speakers celebrating Martin Luther King Day, Black History Month and the election of President Barack Obama. She also helped distribute food to the needy.
At least twice a year, she would also speak to groups about her past struggles and how people should work to fight for women's rights and against discrimination, Roland said.
And she always did it looking her Sunday best. "Matching purse, shoes and accessories. She took pride in the way she dressed," said Roland.
Born in Louisiana in 1950, Dukes moved West at a young age with her mother, who was in search of work. She later married but had no children.
In 1994, Dukes enthusiastically accepted an offer to work the Walmart cash registers part time for $5 an hour. She dreamed of turning around a hard life by advancing, through work and determination, into Walmart corporate management.
"I was focused on Walmart's aggressive customer service," Dukes said in a 2011 interview during her lunch break, after first saying grace over a meal of fast-food hamburgers and chicken nuggets. "I wanted to advance. I wanted to make that money."
When Dukes needed change to make a small purchase during her break, she asked a colleague to open a cash register with a 1-cent transaction, which she claimed was a common practice.
She was demoted for misconduct. She complained to a manager that the punishment was too severe and part of a long campaign of discrimination that began almost as soon as she started working for Walmart in Pittsburg, a blue-collar city of about 100,000 in Contra Costa County.
When those complaints were ignored, Dukes sought legal advice and ended up serving as the lead plaintiff in what would become the vast class-action suit.
Dukes worked for Walmart until last year. Services are pending.
