Halcrow Business Solutions project manager Graham Hindley has persuaded his employer to formally recognise sexuality in its employment codes.
The move is likely to pave the way for partners in same sex relationships plus those in unmarried heterosexual relationships to gain the same pension and medical benefits enjoyed by married couples.
'Though I have never had problems as a gay man there are others who fear their careers may be affected if they come out, ' said Hindley. Halcrow's equal opportunities statement currently addresses all minorities except gay men and lesbians.
'There is a single word missing from the statement - sexuality, ' he adds.
Hindley studied civil engineering at Hatfield Polytechnic and believes that engineering is in his blood - his father was a mechanical engineer. A fascination with buildings drew him to civil engineering.
He describes his decision to make his sexuality public at work around six years ago as the 'best thing that ever happened to me'.
While it has not changed the way he does his job, being able to talk honestly about his personal life with colleagues has made his life far easier.
And in response to issues raised by Hindley since this time, Halcrow has now pledged support for 'all our employees, regardless of their personal circumstances.'
