As a matter of fact, this is the first time I hire a maid and I seldom in this "論盡家傭" topic, so I did not have much information of what I should do on this topic before. I think I should take more time to study here in future ...
When I read through your message, I totally agree that you have to get rid of this maid, certainly no need to continue the contract with her...
Unless she is a superwomen that she managed her housework so brilliant and no need for you to worry...but I bet that her performance is so far so good to you.
