Under common-law rules, anyone who performs services for you is your employee if you have the right to 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. For a discussion of facts that indicate whether an individual providing services is an independent contractor or employee, see Section 2. 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 does not matter whether the individual is employed full-time or part-time.
