LOS ANGELES — A law firm that has battled companies like Intel and Farmers Insurance over unequal pay for female employees is now taking on the Walt Disney Company.

Andrus Anderson, which is based in San Francisco, filed a lawsuit in Los Angeles County Superior Court on Tuesday claiming that Disney discriminates against female workers by paying them less than their male counterparts. The complaint, filed on behalf of two employees at Walt Disney Studios, LaRonda Rasmussen and Karen Moore, asks for back pay, lost benefits and other compensation.

The plaintiffs also want a judge to force Disney to create internal programs to “remedy the effects of Disney’s past and present unlawful employment policies,” including adjusting salaries and benefits for other women and creating a task force that compiles reports on progress. Lori E. Andrus and Jennie Lee Anderson, lawyers representing the women, asked that the case be certified as a class action.

“Women are fed up with being treated as cheap labor,” Ms. Andrus said, noting that Tuesday was National Equal Pay Day, the point in the year at which, on average, a woman’s pay for working in 2018 and 2019 would equal a man’s pay just for 2018. “We hope that this lawsuit will shed some light on the pay discrimination that Disney is subjecting its hard-working female employees to.”
