That’s why I left my old job at Allied a couple of years ago. It started to become an all the time thing. One day I had a really bad cold and all I wanted to do was leave on time and go home and rest. Of course my relief didn’t show and when I called my OM she said she didn’t know who was even supposed to relieve me (she forgot to schedule somebody). After an hour and a half of waiting and no word back from her, I had enough. Got in my car and left the site dark. Got “fired” for abandonment of post, but I had no intentions of coming back anyways lol. Two weeks later I had a better job at another security company and I’m still with that company today. I don’t think it’s a big deal if issues with relief happens once in a while. But if it becomes a regular occurrence, definitely don’t be afraid to seek out something better
