Many states that have wage collection laws have signed agreements with other states to help collect those wages. That means if an employer moves across a state line, or is based in another state, a worker with a wage claim may have help from another state in collecting those wages. Some states regulate specific workplace requirements. Examples of these are when overtime must be paid and for how much, if paid or unpaid break and lunch periods must be provided, on what grounds an employer may terminate an employee, and what minimum wage must be paid to workers in that state. Each state varies greatly on what requirements exist.
States also differ on what level of authority they have to enforce existing laws.
Many laws not enforced by a state agency must be handled by private rights of action in an appropriate court of law. Check with your state for further information. Some states require certain types of employers or contractors to register with their state to do business. Most regulations exist to provide some assurance that the business is operating legitimately within that state. Requirements vary greatly from state to state.
