The ABC test is a three-prong test for establishing employee status. It presumes a worker is an employee unless: (A) the worker is free from the employer’s direction and control, (B) the work is outside of the “usual course” of the employer’s business, and (C) the worker is engaged in an independent trade, occupation, or business. Some states have passed specialized laws that employ the test in certain sectors. See the National Employment Law Project website for a US map shows where the test is used.
