Under common-law rules, anyone who performs services for you is your employee if you can control what will be done and how it will be done. This is so even when you give the employee freedom of action. What matters is that you have the right to control the details of how the services are performed. If you have an employer-employee relationship, it makes no difference how it is labeled. The substance of the relationship, not the label, governs the worker’s status. It doesn’t matter whether the individual is employed full time or part time. To determine whether an individual is an employee or an independent contractor under the common-law rules, the relationship of the worker and the business must be examined. In any employee-independent contractor determination, all information that provides evidence of the degree of control and the degree of independence must be considered. Facts that provide evidence of the degree of control and independence fall into three categories: behavioral control, financial control, and the type of relationship of the parties. Example: Donna Lee is a salesperson employed on a full-time basis by Bob Blue, an auto dealer. She works 6 days a week and is on duty in Bob's showroom on certain assigned days and times. She appraises trade-ins, but her appraisals are subject to the sales manager's approval. Lists of prospective customers belong to the dealer. She has to develop leads and report results to the sales manager. Because of her experience, she requires only minimal assistance in closing and financing sales and in other phases of her work. She is paid a commission and is eligible for prizes and bonuses offered by Bob. Bob also pays the cost of health insurance and group-term life insurance for Donna. Donna is an employee of Bob Blue.
