The Maternity Protection (Amendment) Act 2004 amends and extends the provisions of the original Maternity Protection Act 1994, enhancing various rights for employees during pregnancy, maternity leave, and related scenarios. Key updates include increased maternity leave duration, provisions for additional leave in cases of illness, and rights related to premature birth and hospitalisation of the child. Furthermore, the Act introduces entitlements for time off for ante-natal classes, breastfeeding, and the protection of employment rights during these leaves.

Significant amendments encompass adjustments to the definitions and processes governing maternity and paternity leave, as well as provisions addressing unfair dismissal in the context of maternity rights. Employers are required to comply with enhanced notice and procedural requirements, ensuring that pregnant employees and new parents are adequately supported and protected under the law, particularly concerning job security and terms of employment during such absences.
