Bill entitled an Act to provide that an employee may notify his or her employer that he or she does not consent to retire at the contractual retirement age; to provide that an employer who receives such notification may not enforce the contractual retirement age where the employee is less than the pensionable age unless the retirement of the employee concerned is objectively and reasonably justified by a legitimate aim and the means of achieving that aim are appropriate and necessary; to further provide for the prohibition of penalisation resulting from such notification; for those and other purposes to amend the Workplace Relations Act 2015; and to provide for related matters.
