Employees of game publisher Activision Blizzard will go on strike on Wednesday,
The US state of California filed a lawsuit against the company last week because women face discrimination and sexual harassment in the workplace.
A supervisor spent two years investigating the work culture within the company.
The indictment states, among other things, that women are paid less than men for the same work and are less likely to be promoted.
Several executives have also harassed women.
The state also writes in the indictment that an employee committed suicide during a company outing.
The woman allegedly had a sexual relationship with a manager.
During the outing, colleagues are said to have distributed nude photos of her.
Activision Blizzard called the allegations unjustified in an initial response.
They are said to have been "taken out of context" and also "old".
The company said it has tried to pay employees fairly in recent years.
The reference to the suicide was not fair to the company.
Employees are furious about these statements and therefore announced a strike.
Activision Blizzard boss Bobby Kotick has since apologized for the company's response.
"Our initial response to the issues and your concerns was tone deaf," he wrote in a letter to employees.
"It is imperative that we acknowledge all experiences and respect the feelings of people who have been mistreated in any way. I am sorry we did not provide the proper empathy and understanding."
Kotick has engaged a law firm "to review company policies to promote a respectful and inclusive workplace."
He also announced that every claim is being investigated and that the company will not hesitate to fire people if the allegations are proven to be valid.
Activision Blizzard says it supports the strike.
Employees who go on strike will continue to be paid.
