I think there are three main reasons for the frequent occurrence of nanny crimes in recent years. First, the employment mechanism is unreasonable. Second, there is not enough communication between family and nanny. Third, the prevention work has not been done well.
The employment mechanism needs to be improved. Nowadays, many families don't go to intermediaries to hire nannies, because they also consider handling fees and the like. No matter how good the word is, no matter how low the salary requirement is, an unidentified nanny can't be wanted. Formal intermediary agencies or domestic service centers should have perfect files for every nanny, which requires the system reform of various domestic agencies. Foreign institutions can clearly describe their previous work, family situation, basic information, health status, etc., as well as the previous employer's evaluation of themselves and the reasons for dismissal. For example, taking care of the elderly, taking care of bedridden patients, taking care of children, etc., domestic employment agencies are obviously not so meticulous, which leads to this.
Do a good job of communication in time. There have been incidents in which nannies abused children and poisoned the elderly before. I think poisoning the old man is completely psychological distortion. If you don't want to take care of them, you can resign. However, in the child abuse incident, I think it is very likely that the child is disobedient, the nanny is angry but has nowhere to vent, and the discipline is weak, so this means is used. As a parent of a child, I think we should first educate the child correctly, don't spoil it, and deal with the child's situation reflected by the nanny in time. You can't think that "my child is the best, and all the mistakes are the nanny's". You should respect the nanny.
Finally, preventive work. I think when recruiting a nanny at the beginning, you must first conduct an "interview" or stipulate a probation period, because you will find problems in the process of getting along with many things. If you feel something is wrong, you should get angry as soon as possible and pay more attention to small details. Moreover, relevant contracts must be signed during the employment period to avoid disputes. Many people say that it is not a good idea to install cameras at home in order to monitor their behavior. If we must use this extreme method, it will not only violate the privacy of the nanny, but also break the most basic trust in getting along with others.
