No doubt because employers do not want to hire insane people who are delusional and out of touch with reality. Further, transsexual men pretending to be female have a very high rate of criminality generally and as sex offenders particularly, and these are not the sort of folks an employer wants to hire.

If transsexuals would, instead of seeking surgical mutilation and to twist reality to fit their delusional system, get therapy to put their delusions to rest and learn to love themselves and their wonderful bodies as they are, then they would get hired on the same basis as normal people.
