I haven't heard from boyfriend all day?

Ok so we always talk before he goes to work which is at 8am. This morning we didn't. It was no biggie so I continued sending him funny pictures throughout the day. Well, he hasn't responded at all and he usually does by now. I'm thinking he forgot his phone at home but I'm a little worried. I always hear from him and I haven't. He was also supposed to start his second job today. What should I do? Idk maybe I'm too jumpy but I just want to make sure he's alright. This is very unusual.
