The law states that men and women are entitled to equal pay where they are doing the same work, or, in some cases, different types of work, but which are considered equivalent. These are categorised as:
- 'like work' – the same, or broadly similar work;
- 'work rated as equivalent' – different work, but where the jobs have been rated as equivalent under a job evaluation scheme; and
- 'work of equal value' – different work, but which could be rated as equivalent if there had been a job evaluation scheme.
