Jenna Mueller, SHRM-CP
Human Resources Assistant Manager @ The Salvation Army
About
Human Resources Assistant Manager and SHRM-CP certified HR professional with experience supporting employee relations, payroll, onboarding, investigations, compliance, and day-to-day HR operations for a workforce of 900+ employees. I currently work with The Salvation Army supporting multi-site HR operations across Southeast Michigan, including retail locations, a warehouse, and an Adult Rehabilitation Center. A big part of my role is working closely with managers and employees to navigate workplace issues, interpret policy, and keep day-to-day HR processes running smoothly in a fast-paced environment. My work also includes payroll processing through ADP, handling sensitive employee relations matters, and supporting workplace investigations. I spend a lot of time balancing employee needs with organizational policies, and I take pride in being someone leaders and employees can come to for clarity and support. Outside of HR, I enjoy watching horror movies, spending time with my dog, and working on the novel I am (slooooowly) writing. I am always open to connecting with others in HR and learning from people in the field!
