Security. My sister has a kid. She used to complain about not being allowed to come into the classroom after school. This puzzled me because schools claim that they want parents to get involved in their schools. I would have thought it was an invited guest. I tend to ask people who they are. But, I don't always. I came up to my register and saw a strange guy in button up white shirt and tie. He starts telling me what I did wrong. I'm like looking at him like who are you. He finally identified himself as lose prevention. In other words, he deals with security issues in retail. Why did he not have a name tag? This really bugged me. I suspect that your school could use name tags for staff and visitors. This would help the staff, students and any other concerned person to distinguish between known people and strangers. It wouldn't be too hard would it? Sorry about ranting. But, it really annoyed me when a complete stranger starts pointing out what I failed to do at the register. I mean lose prevention people should know to have a name tag. So that we know that he is employed by the company. I think that if your school feels a desire to destinguish between stranger and known people. Then, requiring staff to wear name tags can help. I was a substitute teacher for a while. No one would know me at the school. I could have been a stranger or substitute. Who would have known? Parents like to visit their kid's classrooms. How can you know all the parents? I would like to think that the school teacher would know most of the parents. But, what if I showed up? I have only been seen once by my nephew's teacher. Of course, I am a twin. So almost anyone would know from the similarities to my sister. Well, I will shut up now.
