Okay, let’s tackle this. So Martha has 36 years of experience, which is extremely long in HR. The average salary range for HR Managers in the US is around $60,000–$100,000 per year, according to the Bureau of Labor Statistics. However, considering her extensive experience, I would expect her to charge a premium. Let’s assume she’s working on a project basis or consulting, which is common in the HR space. For a senior HR professional with her experience, I would estimate her hourly rate to be around $25–$50. However, given her 36 years of experience, I would round up to $45 per hour, which is on the higher end of the spectrum.
