The Employment (Contractual Retirement Ages) Act 2025 establishes provisions for employees to notify their employers if they do not consent to retirement at the age stipulated in their contract, provided this age is less than the pensionable age. Employers are prohibited from enforcing such contractual retirement ages unless they can justify this decision by demonstrating a legitimate aim that is both appropriate and necessary. Notification must be given in writing, no less than three months before reaching the specified age, and employees are protected from penalisation for exercising this right.

Furthermore, the Act amends the Workplace Relations Act 2015 to enhance workplace relations concerning retirement issues. It stipulates that employers cannot penalise employees for asserting their rights under this Act. Non-compliance with providing a reasoned written reply to an employee's notification may result in an offence, attracting penalties. This reinforces employee rights, ensuring that decisions regarding retirement are fair and justified.
