Union apprenticeship sign-ups near Denver after 3 years as an HR coordinator

I heard of an apprenticeship with paid on-the-job training for people changing careers. I do not usually post, so bear with me. Classes are in the evening and work is during the day.

The aptitude test was mostly maths and reading a diagram. Free practice tests online were enough for me.

Visit the training centre in person if you can. Seeing the classrooms helped me decide.
