Different rights between ordinary maternity and additional maternity leave?

Ordinary maternity leave typically provides a set period of leave, often around 26 weeks, during which a mother is entitled to receive maternity pay and job protection. In contrast, additional maternity leave extends this period, usually for another 26 weeks, but may not always include pay, depending on the employer's policies and the employee's eligibility. While both types of leave allow for time away from work to care for a newborn, the rights and benefits associated with each can differ significantly, particularly regarding compensation and job security.
