The Connecticut legislature recently passed a bill (which the Governor encouraged and promised to sign) which will ban discrimination on the basis of gender identity or expression in employment, public accommodation, housing, credit, and other areas, and would apply to any public or private employer that employs three or more people.  The law will go into effect on October 1, 2011.
