The top official at the Texas Department of Agriculture (TDA) has issued a memo telling workers they must dress “in a manner consistent with their biological gender,” according to a copy of the document obtained by the Texas Observer. The order — the latest attack by the Republican-controlled state government on transgender and gender-nonconforming people — was delivered to TDA personnel last Monday, according to the Observer. It includes a threat that they could be fired if they don’t comply, the memo shows.
