It is against the law to discriminate against an employee on grounds of sexuality. If you feel you are experiencing discrimination then you should keep a record of relevant instances, when they occurred and who witnessed them. Then, if you have to raise the matter formally, you can support your case with specific examples.
If you do formally complain about your treatment you can use your company's grievance procedure. Under this procedure you have a legal right to be accompanied by a work colleague or a trade union official to a meeting.
If you can’t sort things out with your employer you can present an unlawful discrimination claim to an employment tribunal, but you must do this within 3 months of the act complained of. If the discrimination has been continuing, the time limits may begin from the date of your last complaint.
