I was just hired into this payroll role with limited payroll experience, and my co-worker does not have the time to teach me payroll fundamentals from the ground up. We're trying to come up with some ways to learn payroll fundamentals through online courses or resources inexpensively. We use Ultipro, and while Ultipro does have a great, extensive training program. It's more geared towards learning about using Ultipro rather than learning payroll. What are some courses or resources that worked for you?
