Federal Agencies and how do they address Gender Transition in the workplace?

In my Agency, USDA , we are looking to develop an Agency wide policy to address individuals that are experiencing transgender reassignments and the impacts within in the Federal Workplace. I would like to open a dialog with representative of other Federal agencies as to their existing policies and the success of such policies. The end result will be a process that allows our Special Emphasis Program Managers a foundation to develop a written policy in USDA. In this context dialog discusses not over the moral issues of if employees should be allowed to transition in the workplace, rather we are acknowledging that the process is of social importance to look at from a perspective of engaging dialog to the necessity of participating in the social contracts of the federal workplace. Where we, as federal employees, must set aside our personal biases and perceptions when we come to the workplace and where every employee has a level of security and protection to be a worker amongst workers. I’d like to hear about how your Agency has become forward thinking in this subject.
