just share my understanding. its actually depend to your company policy. in the ea, it actually stated after completed the course of 12 months, you will be entitled.
but if your company say you can enjoy after probation means yes, if not, u have to complete the whole year lol.. BUT you will still have the leave with you. until u are resign, the total leave will be prorated until the current months. your employer also have the right to set the bring forward of annual leave..
please correct me if i am wrong..
