Very part time second job, do I need to update my tax papers?

So have a question that I saw a possible answer to here but it’s a bit of a different situation so maybe somebody can give me a more specific answer.

I got a part time barista job first. Max 20 hours a week. Then I was offered a full time, 40 hour a week, Monday through Friday admin position. Since I was anticipating quitting the barista job not long after accepting the admin job I put on my onboarding papers at the admin job that I do not have a second job. There is an overlap between the 2 jobs of about a week, only working 10 hours at the barista job and about 30 for the admin.

Now here is where the question comes in; I talked to my boss at the barista job and he said I can work weekends by picking up unclaimed shifts. I would be working at the most 7 hours a week at the coffee shop but likely even less with weeks I do not work there at all. Do I need to update the tax papers at the coffee shop to reflect that it is a second job? The admin job is definitely my primary job and the barista job second but would I be working enough hours at the coffee shop that it would even count for anything? Not including tips, I would be making less than or just about $100 a shift with tips bringing it up to maybe $150-$200 depending on how busy it is.

Thanks so much for any help sent my way and I can give more context if needed!
