More than one in three trans people have left a job because of discrimination at work, according to a new report.
A study of 400 trans people by website totaljobs found that 36% had quit over discrimination and half had hid their gender from colleagues.
Discrimination was most likely to come from fellow workers, followed by managers.
Half of those surveyed said understanding of trans workers had improved.
John Salt, of totaljobs, said: "We hope that the findings of this report will generate further support and greater awareness of the employment issues facing trans workers, but clearly there is more to be done.
"Sadly, discrimination in the workplace has been compounded by a lack of support from employers.
"Our survey reveals that more than a fifth of employees said that there was no provision for trans people at their workplace, and 24% had received no support or guidance from their HR departments when transitioning."
