For Central/State Government/PSU employees, separate rules are framed for maternity benefits, and they do not fall under the Maternity Benefits Act. For government employees, the number of days of maternity leave is 180 days, whereas it is just 84 for employees in establishments covered by the Maternity Benefits Act. Similarly, there are some 365 or 730 days of leave which can be availed at any time before the child becomes a major! These cannot be included in the Maternity Benefits Act meant for employees in the private sector, and if included, I don't think it will be feasible to run the organization with female employees. Of course, under government rules, there are restrictions regarding the number of issues, which is anyway not there in the Maternity Benefits Act.
