I hate my stupid fucking job

6 months into my job and I’m miserable. So much demand, so much pressure and so much walking. I’m so exhausted I’m usually stuck working all by myself and even when I’m not by myself, I’m stuck with incompetent coworkers. I just wish they weren’t so fucking weird and would just do their job right. Customers are so fucking demanding too and I’m sick of running around, losing my mind over them. Worst part is, my main supervisor we all hate was on temporary leave but is now back. We were so well off without them and since they came back, we’re back with the same bs. Management doesn’t even care even though they know we all hate our supervisor. Anyways, summer is around the corner and it’s gonna be busier than it’s ever been. They’re starting to force me to do stuff I didn’t apply for/stuff I haven’t been properly trained to do. This job is honestly getting away with a lot of shady shit, a lot of people from other departments are usually complaining about similar problems. I’m just so sick of it but I wonder if I just need to get over it. No job is ever going to be perfect. I’m really satisfied with a lot of benefits and conveniences my job has but damn there is so much annoying shit too. I’m just so over it and I don’t know if I should bother looking elsewhere
