My 2 kids love the ex maid a lot (She have been taking care my kids from new born till 5 years old). But I fired her when my eldest kid was 5 years old. I told my kids that the maid was pregnant, therefore she need to go back to Phillipin to get birth, but after all, she will come back again. (Of course it was a lie).
Till now, my kid still asking me when she will come back...... But I am sure they can forget her in a day.
I suppose fired her when my eldest kid was 3. According my kid love her so much, therefore I kept her till 5.
For lay off, that means there will be no replacement, then you'll need to pay severance. To be eligible for 長期服務金, the maid has to complete service of 5 years. If kksa fire her, she may sue her for avoiding to pay 長期服務金, but, she has good reason for objection as she renewed her second contract, which mean she has prepared to pay her 長期服務金, but just because of her bad performance, she determine to fire her. The timing is just an coincident.
