I'm going to push back against this pretty strongly. Yes, an applicant needs to check off X clinical hours and Y volunteering hours as a minimum to show that they A) know what they're getting themselves into, and B) have at least a shred of altruism in their body, respectively. But it's overly reductive to suggest that those are the ONLY things that matter in the med school application process.
There is absolutely value in having a "real world job" before applying to med school, and doubly so when it is clearly a job that is adjacent to medicine like this job would be. In an interview setting I could imagine the OP being able to more clearly articulate an interest in, say, pediatrics or psychiatry based on this experience. There is a level of responsibility that comes with holding down a job that doesn't exist when you're "just volunteering," particularly in a job that would require critical thinking and direct person-to-person interaction.
So, yes the OP needs to check the boxes in some other way, and if they still need to study for the MCAT then they need to make sure they aren't overexerting themselves. But assuming they can do that, this is the kind of experience that can really help an application stand out from all of the hundreds of applicants who got 1000 hours scribing in the ER. There is nothing wrong with scribing, but the applicants who did that kind of all sound the same in an interview, whereas the OP will definitely have a unique and memorable background.
