I sponsor $50 for my maid to add value on her People card every month because I will contact her when she goes out with my son. I order her to turn on the mobile phone when she goes out. Later, she told me " it's cheaper to join the plan offered by some 電訊 company. I replied " I know some plan is 1,000 min every month, but my average telephone usage would not exceed 500 min every month" Do you think the maid would think on the side of the employer? It's better for her if the tel usage is 2,000 min, then she can talk 70 min per day. Most of the maid often try to test our bottom line and take our advatage.
