Discrimination against travellers and on grounds of gender now dominate cases being taken under the Employment Equality Act.
The finding is contained in a review by the Equality Authority, published to coincide with the group's third anniversary.
Discrimination against travellers features in almost 66% of cases dealt with under the Equal Status Act.
The main issue is access to pubs and hotels, but there have also been complaints in relation to insurance, accommodation and education.
Almost 36% of employment case files taken under the Equality Act relate to gender discrimination.
Key issues relate to discrimination against women during pregnancy, sexual harassment and equal pay.
The review by the equality authority shows that migrant workers are also particularly vulnerable to discrimination, making up 27% of cases, in areas such as equal pay, working conditions and dismissal.
Disability also features prominently dealing with issues such as access, dismissal and harassment.
