Worth paying for a certificate? after 11 years as a barista

I saw that many postings ask for a specific certification. I do not usually post, so bear with me. I can study evenings. Did a certificate help you get hired?

The workforce centre told me about training funds I qualified for. It covered most of my course.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
