Organisers of a series of walkouts in protest at Google's treatment of women have said they have since become victims of retaliation by the company.

Axar.az reports citing foreign media.

In November, 20,000 employees walked out of their offices demanding several key changes in how sexual misconduct allegations were dealt with at Google.

Now, in an internal email published by Wired, two of the employee activists behind the protest accuse Google of retaliating against several organisers.

Google denies retaliating in any way.

Employee activist Claire Stapleton, said she had been demoted from her position as marketing manager since the protests.

"My manager started ignoring me, my work was given to other people, and I was told to go on medical leave, even though I'm not sick," she wrote.

"Only after I hired a lawyer and had her contact Google did management conduct an investigation and walked back my demotion, at least on paper.

"While my work has been restored, the environment remains hostile and I consider quitting nearly every day."
