How do you find an employer that will let you transition on the job? Or that will hire a transman or transwoman? If I were starting out, I would look at companies that value diversity. Who are they? Look at the DiversityInc Top 50 for a start.
Don’t expect any of them to hire you because you are transgendered; that would be a fantasy. Instead, the most any of us — any color, any race, any (trans)gender, any religion, any age — can expect is that we will be considered on the strengths of our accomplishments, skills, and abilities, without pre-judgements based on color, race, gender, religion or age.
My own employer, The New York Times, didn’t make the Top 50, but they impressed me — long before I realized I was transsexual — with their commitment to mixing up the workplace with respect to gender, race, and cultural background. It should have come as no surprise that they accepted my transsexualism as a normal part of doing business.
Don’t expect to find job openings for “Transgendered Plumber” or “Transsexual Accountant” anywhere in this universie. Do expect to find focus on skills, not labels, at companies that value diversity.
