The Federalist recently published 19 insane tidbits about the Google office environment gleaned from the James Damore lawsuit.
Keep in mind I’m a programmer, not a lawyer, when I say that Damore has a prima facie case of illegal retaliation: he engaged in protected activity — i.e., exercising the right to improve working conditions — by opposing several discriminatory practices, and was fired from his job.
Damore wrote in his famous (or infamous) memo that “Google has created several discriminatory practices.” Classic case of opposition to an unlawful employment practice.
The law does not require that the employment practice actually be unlawful, only that the employee believes the practice to be unlawful.
