Which short course helped you get hired? after 13 years as a security officer

I saw that many postings ask for a specific certification. This is my first time dealing with any of this. I would like to use funding if possible. Which ones are overrated?

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.
