Final answer:
Under the ACA, a full-time employee is defined as one who works at least 30 hours per week or 130 hours per month, and employers with over 50 full-time employees must provide health insurance.
Step-by-step explanation:
Under the Affordable Care Act (ACA), a "full-time employee" is described as someone who works an average of at least 30 hours per week or 130 hours per month. The employer mandate of the ACA requires all employers with more than 50 full-time employees to offer health insurance to their employees. This element of the ACA aims to increase access to health care coverage and reduce the number of uninsured or underinsured Americans. It's an important aspect of the law as it addresses gaps in healthcare coverage, ensuring that more employees have access to health insurance through their employers.
