Can he get Transpeople on the list of federally protected people for federal contractors and the general work place? Write a friggin' Executive Order?!
Remember that if you work for a larger employer (generally 15+ employees), you are protected under Title VII of the Civil Rights Act. You can file with the EEOC if you face discrimination.
However, I agree; it would be good if we had an EO covering even small employers who are getting federal funding.
