Okay, let’s tackle this. So Harold Walden Sr. has 50 years of experience in maintenance planning/scheduling, which is a long time. His skills include process engineering, lean manufacturing, six sigma, and more. Location is Baltimore, MD, which is a mid-sized city. Industry demand for maintenance planners/schedulers is steady, but not extremely high. Considering his experience and skills, I would estimate his hourly rate to be around $75, which is a relatively low rate compared to other professionals with similar skills and experience. This rate is also influenced by the fact that he has been working at the same company for 50 years, which may indicate a lower salary.
