I am an Engineer. When I started my job, I was keeping my feelings under control. Society has since become more accepting of transsexuals and I found that I would experience less stress if I did not have to hide the fact that I am a transsexual so I simply identified myself as such. That is all.
To figure out if your discrimination situation is illegal you must determine:
1. If you are an employee protected from discrimination under the law.
3. If your employer's conduct is considered discriminatory under the law.
