I have achieved numerous sales recognitions at Paychex and I served as President of our Toastmasters Club for 2 years. I am most proud of the many clients I have helped make their companies the employer of choice through our services.

I love working with small business owners because each business is unique and so are the owners, but they all have the burden of recruiting and retaining top talent plus managing their companies. Each company has their own internal and external challenges as owners navigate the changing landscape of HR regulations. I’m passionate about supporting small businesses because of my insight personally and professionally.

Janet Justice – Paychex HR Services Sr Human Resources Generalist

Human Resources

Janet JusticeI am originally from the Philadelphia area. I graduated from West Chester University of PA with a degree in Spanish. I spent my junior year studying in Madrid, Spain, and unfortunately 30 years later, I can barely speak a word of Spanish. Hola and Gracias are about the extent of what I remember.

I have been with Paychex for 19 years. I started my career in the Allentown, PA office as a payroll specialist, and later worked in Piscataway, NJ, and Rochester, NY in the Online Services division, in such roles as tech support supervisor, project manager, and other management positions. I have spent the last 8 years working in the Fairfax, VA office, moving there as the Client Service Manager for Payroll Operations, and stepping into the HR role just over 4 years ago. In this consultative position, I have the pleasure of visiting clients at their worksite. I provide guidance, support, and resources to help business owners navigate common HR practices and issues. In my management positions, I knew the “joys” of hiring, firing, employee relations issues and everything else that goes on during the employment lifecycle. As an HR professional, I really love what I do. I can draw on my personal experiences as a manager, but I’m no longer on the front lines dealing directly with these management tasks. Now I just get to tell others how to do them.
