Hi Ellysia,
last month, i discussed with my boss regarding maternity leave. according to my boss, there is no need to formally apply for maternity leave. When we go into labour, just call back to office to inform them. They will let me know when the 8 weeks expires and the next day I need to be at work. If I want to use up the next 22 days (3rd maternity month) immediately after the 8 weeks expires, I need to go back to office to fill in a form for maternity leave (we have a standard form to tick whether it is annual leave, urgent leave, maternity leave, childcare leave, no pay leave).
my boss and I already discussed in general how I will be spending the 3 months of my maternity leave and are in agreement. I also told her how I wish to spend my childcare leave and annual leave. Of course, it is just a general understanding. I told her it may change and she was understanding cos I also need to sort out childcare arrangements and it is not a striaght forward 3 months leave mah.
you may want to check with your HR dept and speak to your boss. I'm not sure if all companies work the same way.
