Two employees of The Walt Disney Co. have filed a class action alleging that its studio entertainment division systemically underpays women, compared with men.

The complaint, filed Tuesday, which was observed as Equal Pay Day, alleges that Disney treats women as “cheap labor,” paying them tens of thousands of dollars less than male colleagues. The two plaintiffs, both women, brought the lawsuit on behalf of a class of thousands of current and former California employees of Walt Disney Studios, which has offices in Burbank and Glendale, as of April 1, 2015.
