They do ask your "gender assigned at birth" now on many documents.
I did an online survey at work about job satisfaction
First question was "Gender" and gave options "male, female or other"
I ticked male, next question was "was this the gender you were assigned at birth?"
WTF has this got to do with my satisfaction with my job?
I went back and changed male to female and answered "yes" to the second question
So my company now thinks Im a female from birth
