There is no legally mandated retirement age in the private sector. The age at which private sector employees retire is a matter for the contract of employment agreed between them and their employers.
Employers must justify the age of retirement under the Employment Equality Acts 1998-2015. Section 6(3) of the Employment Equality Acts 1998 to 2015 provides for the imposition of a compulsory retirement age, however, it must be objectively and reasonably justified by a legitimate aim and the means of achieving that aim must be appropriate and necessary. An employee may take a complaint to the Workplace Relations Commission under this legislation if they consider they are being discriminated against.
