What a co incidence! This happened to me last month. My Bun also handed me resign letter. I asked her why and she said her husband has 2nd wife and they took away her two kids! Thats why need to go back and sort out. Then I asked if her relatives, parents or even police can help. She said cannot, but if the employer (me) allow her to take leave, then she promise to come back after 3 weeks.
Finally I offered her 2 weeks leave and she promised to come back. The reason why I dont want her to resign 1. my baby likes her 2. She's quite hard working 3. I dont want to take risk by hiring another maid
Now I need to take 2 weeks off to take care of baby and I lost half month salary...... so sad!
