652.110¹
Method of paying employees

• agreement on method of payment
• revocation of agreement

(1) A person engaged in any business or enterprise of any kind in this state may not issue, in payment of or as evidence of indebtedness for wages due an employee, any order, check, memorandum or other instrument of indebtedness unless the instrument is negotiable and payable without discount in cash on demand at some bank or other established place of business in the county where the employee lives or works and where a sufficient amount of funds have been provided and are or will be available for the payment of the instrument when due. The person shall, upon presentation and demand, pay the instrument in lawful money of the United States.
