Should I include the job I’ve been working at for a month on my resume/application?

I started a job a month ago for some quick cash, hate it, and am looking for something better. It’s at Walmart. I need an income coming in but don’t really want a short term job on my applications/resume. I left my last job a year ago.

Would it look better to say I am working here just to say I’m employed? Or should I pretend to be unemployed? The job is a huge step down from my last role and while not embarrassing, I would struggle to speak positively of it in an interview.
