I work as a security guard and my job has a no phone policy. I can understand not using my phone at a busy work place where customers are at. But I work a post where I do patrols every 2 hours and I have nothing to do in between. I still use my phone anyway but I'm paranoid my supervisor might come by and fire me. But I rarely see them anyway and they seem pretty chill about it. I just hate working at jobs where I constantly have to look like I'm working.
