AITA for being pissed off for being forced to come to the office?

Hi this is my first time posting here and I genuinely just wonder if I’m wrong or not.

We have this situation at work where one of our coworkers is sick and can’t come to work. That naturally means someone has to cover her shift instead. We work in a hybrid model where sometimes we work remotely from home or have to go to the office, every shift is 12 hours, our job has to be covered 24/7 due to the nature of it (logistics). I’ve had this situation where without any agreement I was forced to come to the office instead because the person covering my coworkers shift was away from the city. Sure that’s no biggie. Now that same coworker has extended her sick time because well she’s still sick which is understandable. The thing is someone had to cover her shift again and that said person agreed to cover it only on the basis that he’s gonna work from home. Now I’ve just had like 4 out of 5 days in the office because of that and now I’m being forced to come to the office AGAIN even though according to our schedule I was supposed to work from home. I got annoyed by this and talked about it with another co-worker that I was switching shifts with. I said that it’s unfair that I’m being forced to come to the office instead when the person who’s going to work remotely is getting paid extra and while I’m sacrificing an hour from my time to get to work + money for bus tickets I don’t get anything out of it. I feel like they don’t value me as a co-worker. I do live the closest to our job, but it’s still my private time and my private money that I have to invest. My coworker that I complained to started arguing with me that I’m being unreasonable, that they have to do way more stuff as shift leaders (which I am not) and they barely get any extra money out of it which has nothing to do with working from home. Then he complained that the extra money he earns in his case goes for fuel for his car, he made the problem about them as shift leaders. I think it’s his problem since he commutes to work by car instead of public transportation which is cheaper, but longer. I don’t think it’s my problem that they don’t earn enough extra for being shift leaders, I think they should be complaining to our management instead of agreeing with everything and then thinking I should be doing the same or resign from the position if they hate it so much. I used to agree with everything at work only to be taken advantage of. I know my coworkers only think about themselves and when I do the same they get pissed off at me. The other person who’s covering my co-workers shift doesn’t go to work by car, goes to work by bus and is at his house (he literally admitted that to me on his shift).

Am i overreacting? Am I the asshole here?
