I think u can give warning letter for her first (of course discuss with your agent). Then u employ another new one siliently. If u employ a new one through same agent, u should ask the agent keep secret. Then when the new one come, fire her immediately. If she 嚴重犯錯, u can fire her and no need give one month salary. But ticket need to pay. Detail u can discuss with agent, ask them to suggest u.
Maid only performed worse and worse. So if u find her bad performance now, then she will keep bad and bad gradually.
She already got two warning letter lar, first time was when we received the demand letter from the credit company. This time the agent also issued her a warning letter too...
