Throwaway account for reasons..

I've been at my job for a little over four years and I love it. But I feel like I do way more than some of my coworkers. I work 3 jobs within my job they only work one. But for that one job I am the main person to come to when they need information for it (it is computer based, and I know a lot about the data for it) or when things go wrong.

It just feels like I pick up their slack a lot, and none of them want to help me. I've tried teaching them the things I know, but they either don't understand or don't care.

I just wish sometimes that I could go to work and just do my job without having to worry about other people, fix mistakes other people made, or do extra work.

I know I've been extremely vague, but it just comes down to it. AITA for wanting to work as hard as I do. And yes, my coworkers know how I feel but they don't seem to care.
