Is Marjorie an employee-agent or an independent contractor-agent of PDC? Explain.

Marjorie was recently hired to drive a deliver van for Pick-em-up Delivery Co. (PDC). Marjorie must provide her own van, which must meet specific size, design, and color requirements of the contract. Each day, PDC gives Marjorie a group of packages to deliver, and she must deliver them all within the specific time ranges that PDC has provided its customers, but the company does not tell her what hours she must work, what route to take, or when she can or must take breaks. PDC does encourage drivers to take the shortest routes, to save gas and money, and similar cost-saving admonitions. Marjorie’s delivery area may be changed by PDC with five days’ notice. She is paid based on a combination of factors, including how many packages are delivered, punctuality, and other performance-based parameters. The contract between Marjorie and PDC is an independent contractor agreement.
