My mom's current maid is going off this June, but we want her to help us train the new maid for about a week before she go off as she has been with us for many years. The one issue is she uses her phone very often throughout the day, not after she finish her work. My mom has been very lenient with her about phone usage. She doesn't talk on the phone but message and stuff. So for the new maid, we only want to let her have her phone at night after she has finish all her work. But we don't know how to do it as the current maid and the new maid will be together for a week. She will surely see our current maid holding her phone the whole day. Any suggestions/advice? Thanks in advance!
